My rod ends from Speedway were delivered Monday, so I was able to build the rear panhard bar. I already have the bracket tack-welded to the axle housing and already have the frame bracket ready to go (see above), so all I needed to do was fabricate the bar.
I clamped the frame bracket on the right frame rail and used a straight edge to locate it where the bar wont hit the front of the "chunk". I want to keep the bar as level as possible with the frame at proposed ride height. After a couple of minor adjustments I got the bracket where I want it. I measured the distance between the holes; this is the finished length I need between rod end centers.
I fabricated the bar in the same manner as the radius rods and panhard bar up front, using fine thread coupling nuts and 1/2 inch black iron pipe. When finished welding and grinding I installed the rod ends and bolted the bar onto the brackets. After re-confirming the location of the frame bracket with the actual bar in place, I tack-welded it to the frame.As viewed from the front the bar is level; as viewed from above the right end (frame end) is a couple of inches ahead of the axle bracket. That was necessary for clearance on the front of the "chunk", but will have no effect on handling or operation.

Nice work. Do you have any plans to make those mounts double shear?Ryan

Looks great Jim. I'm going to use the "strap gussets", and a bunch of your other ideas, on my T Bucket.Steve

40FordDeluxe - No plans for making the brackets double shear. I've been doing these the same way for years and never had a problem. Angle iron is roll-forged so it's pretty tough stuff to begin with and the 1/4 inch wall stuff is really stout.I keep the length of the brackets as short as is practical so there is little to no flex and I use grade-8 bolts for all suspension attachment. I think you could rip the frame in two easier than you could break a 1/2 inch grade-8 bolt...
Driver50x - If you can use any of my ideas and practices on your build, then this thread is worth my efforts.You're building a T-bucket; have you seen my build thread on my Track-T? Also, have you considered doing a build thread here on your T?

I'd have to vote for double shear on any Heim joint used in suspension loaded brackets-------It eliminates the sideways force on the heim outter ring--------

Yes Jim, I read through your entire Track T thread. Lots of good stuff in there. I have already started my own thread.

I have seen a considerable amount of concern over using Heim joints for Street Rod suspensions on this and other forums. I think they are very safe. I've seen them used for many years in all types of stock car racing. Those cars get major abuse and pounding on, and I have never seen a Heim joint fail other than in a major wreck.Steve

Jerry - I don't disagree. I use double shear brackets in areas that receive constant stress (my truck arms are in double shear at both ends), but the panhard bar is not stressed beyond the strength of the Heims, bolts, or brackets and I've never had a problem. Maybe I'm living on false security..?
Driver50x - I raced stock cars off & on for 35 years and used a lot Heim ends. I never had one break and some of them took some pretty good hits. I will admit, though, that I generally used 5/8 and 3/4 Heims, not 1/2 inch.
One thing that can be done to make Heim joints safer - put a retention washer on the outside so if the ball somehow slips out of the outer ring it still can't come completely off. In fact, if you put your car through a NSRA safety inspection, they require retention washers on all Heims.Jim

The last of the bracketry needed to finish the rear suspension is the lower coilover mounts. All the ones I found online are too short and would have raised the rear of the car way higher than I want.Also, their shape would have conflicted with my truck arm mounts so they would require modification. The best solution to my conundrum was simply to fabricate my own.
I began with a piece of extra-heavy duty angle iron. It is a scrap that was given to me a few years ago. It is 3 inch x 2.5 inch x 5/16 wall angle. I laid out the shape on the angle and cut it with my 4 1/2 inch grinder with a cutting wheel. This tool is my new best friend for fabricating brackets.For years I have been cutting stuff with a torch or plasma cutter and then spending hours grinding - not any more! In the time it would have taken me to drag out the torch set, cut the pieces, and deburr them for grinding, I already had them cut out and finish ground to size.
Next step then was to drill the necessary holes. I put 5 holes in each one so there is plenty of available adjustment. Combined with the adjustability of the coilover springs, rear height adjustment will be infinite.Jim

That's funny. I watched a friend of mine cut his cab to stretch it with his death wheel a while ago. Ever since, I've used up about 2 100 boxes of them.You just have to respect them as he says. Haha Nice work on the brackets.

Finally, I installed the brackets onto the rear axle housing. I set them so the coilovers are tilted approximately 15 degrees from vertical. The finished brackets are turned so the gusset side of the angle is away from the truck arm brackets. This affords enough room between the brackets that I can weld them completely.
I propped the brackets in place with some wood blocks and my welder's angle magnets and used an angle finder to make sure they are vertical both ways. I will roll the rear end out from under the frame later and finish-weld everything. For now, I just put a few good heavy tack-welds on the shock brackets to hold them in place. All that remained was to bolt in the coilovers and remove the wood blocks that have been supporting the frame.Jim

Yes, Ryan, I have watched people use them before, but just never tried it. Boy, was I missing the boat!One thing I did, though, I left the guard on mine. It's easily adjustable, so I just turned it to one side out of the way. As I was cutting it was covering the top part of the blade. It's still an aggressive tool, but at least it won't hit me in the face if the blade scatters.

I left my guard on too. I have one pneumatic die grinder with no guard that I'll use occasionally with a face shield and caution with a death wheel. I've seen a few flying past me and respect them.
Nice work getting the coil overs on.Ryan

I've not heard the term death wheel before. It's an apt moniker. I've disintegrated many dremel wheels, and partially fractured 4 1/2" discs. Kickbacks are the worst, and probably are the main cause of disc failure and injury. No matter how much I try to avoid kickbacks, they seem to be a calculated risk.
Attention to task is the best prevention, safety goggles and ear plugs are the minimal PPE..
Education is expensive. Keep that in mind, and you'll never be terribly upset when a project goes awry.

I had not heard the term "death wheel" before either, but maybe it's somewhat appropriate. I have not personally heard of anyone being killed by one of these small discs exploding, but I suppose it's possible. More likely, the flying shards could cause severe cuts or could take out an unprotected eye.
Kickback is generally caused by the blade binding in the cut because either the cutting tool or workpiece moved and caused momentary misalignment. Although it is almost impossible to eliminate 100% of kickbacks, the frequency and strength of them can be reduced if the workpiece is solidly held in place while cutting. I cut these brackets while the workpiece was held in a vise. Cutting thin stuff (sheet metal) is another challenge because it can flex and bind the blade no matter how solidly it is held. Firebird77clone said it right - attention to task and proper safety equipment.Jim

Sadly I have seen the result of what damage a cut off disc on a guard-less grinder can do. One of the guys in the hot rod club I was in was lying on his back with his head up under the dash of his '57 Chevy trying to cut something when the whole situation turned nasty. The result was the disc and machine slicing down his cheek and neck just missing his eye and deep enough to see the bone structure. Luckily, no major blood vessels hit and we have an amazing air ambulance system here in NZ. But he is not the handsome young man he use to be and has the scares to tell the story.I maybe a little crazy but it stops me going insane.
