Posi, is a GM term for limited slip. what your talking about is a spool, which no factory 9" came with, that'a an aftermarket thing, and there not safe for the street ( in most cases )

thanks for the info Matt.
I know I called my brother in law in NC yesterday afternoon (he was at the top of the grand-stand at Daytona when he answered his cell phone) and this is what he was telling me about "welded together" maybe thats what he meant with what you were saying about the spool. I don't know a whole lot about these things, but with help from you guys and my brother ( who happens to be at the north slope of alaska right now, so I cant get ahold of him much) and my brother in law, I'm learning alot.
Thanks again

I'd like to say something about my big brother Bob. I hope it doesnt bore ya's. He has always worked on lawn mowers every since he was 4 or 5 and helped my dad. When he was in high school, his one teacher had him fix his car insted of taking an exam for the class because he said Bob would more than likely never care about the things he was told in "Problems Of Democracy" class which all seniors here in the local schools have to take. He got an "A" on the exam for fixing the car. He went into the U.S.Army(just like me and all the other men in my family) and was trained as a motor pool supply clerk. (I was a medical specialist, my dad was an engineer, and my other brother was a tank turret mechanic). In August of '90 he was at FT. Bragg, NC, and was sent to KKMC, Saudi Arabia for the Gulf War. Nobody there knew how to do the high level maint. on the vehicles, so Bob volunteered, even though he was just a "clerk". They gave him a sergeant for an assistant (Bob was sp4) and the 2 of them did the job. When I would write to him, he would tell me about the wrecker that he had with a .50cal machine gun on top that he drove. When he came home in '91, they gave him the Distinguished Service Cross for what he did over there. They said he went beyond the call of duty by volunteering for something he wasn't trained for. The 2 guys (Bob and the sergeant) kept the whole battalion 98% ready for the entire war. He spent 36 hours straight pulling vehicles out of the mud, and he up-righted a flat bed semi truck with several million dollars worth of satellite equipment without hurting anything, saving the equipment which they thought was ruined. (only Bob and one other person in the battalion got the DSC). He keeps his medals in his sock drawer. I seen them one time, but he doesnt talk about them. When he got home, they sent him to Ft. Richardson, Alaska, where he worked on heavy machinery in his spare time. They would also send him to different gold mines to fix equipment. I heard they would send a helecopter for him whenever they needed him. Now he's out of the army, and lives in Clovis NM. He works for CM2H Hill (or CH2m Hill) at Barrow on the north slope of Alaska. 21 days on and 21 days off. He works on anything with a motor. even though he's never been good in school, he's the smartest mechanically inclined person I know. And a damn good big brother.

Thanks for leting me bother ya's with this

here's somepics of what we have done now. (my nephew Justin has helped me ALOT). We added some on to the front of the frame for spring mounts. I finished one of the spring assemblies, and we put all the tubing end pieces in to plug the end holes. cleaned up and painted the front axle. the bike in the picture is another project I was working on. It's a 1976 Honda CB750 Four. It still needs some wiring and it needs the carb cleaned and a couple case bolts. chopped up the frame and made a new oil tank, added sportster tank and harley fender. Justin got me the fat bars for Christmas, and I put on forward controls.
I also have a sailboat to finnish, and a Large format (8x10) field camera to finnish building.

Takes a lot of huevos to start a project without a plan, I just gotta say......RIGHT ON!!

Sam my first bike was a 72 Honda 750. Excellent bike. That thing took me cross country. Love that bike. Your brother seems like a great guy who has some natural talent. Looking foward to reading this thread. Steve.

I got it in stock condition from a guy for $50 a couple years ago. I seen a lot of sites on the internet about chopping the cb750 four SOHC bikes, and wanted to do something with it. this is what it turned out like. here in Mich., you cant have the top of the grip of the handle bars more than 15 inches above the highest point of the seat, so ape hangers are illegal, but I like the lower ones without much rise better anyways. tried to wire it like a santee basically. need to hook up the headlight, and a tail light still. have to adjust the clutch too. the headlights from a suzuki. the original speedometer fit in the top perfectly. I seen somewhere that the 69 cb750-4/sohc was considered #3 bike of all time, and only 3 because it was "too boring to ride" because it ran "too smooth" and had very few problems. Thought about building a hard tail some day maybe.

... and the white-wall (the stripe) is fake....don't tell anyone!!! all the real white walls I could find said "harley" on the side, and Avon tires cost way too much.

I still think it was the most dependable, easiest to maintain bike I've ever owned. If I could find a mint used one I'd buy it in a second!. Those quad carbs, and straight 4 blocks produced some kickbutt accelleration, and it handled better than my current Harley! Thanks for the trip down memory lane!

Big huevos might be an understatement, but am in your court too. I plane to follow this one up. Good (parts) hunting!

Great videos Sam. Thanks.

been looking around for a 9-inch rear end disk break conversion kit. all of them seem to be around $375. I found out that if you get them, they only work with up to 6 1/4 inch axle flange, and the flange will have to be cut/ground from 7 inches for them to fit. that means 3/8 cut all around the flange and it will only leave about 1/8 inch of material outside the bolt pattern.
I checked on some Dana 44 rotors from a '78 F150 4WD and they fit around the center axle, the bolt pattern is the same, 5-5 1/2, and they can hold an axle flange up to 6 5/8 inches. That means the flange only has to be cut/ground 3/16 inch, all around, leaving 5/16 inch of material outside the bolt pattern. They are $40 each for the rotors, and that's for Duralast with thicker disk so it can be resurfaced if needed. I can make a bracket like the ones in the kits that bolt on (not welded) out of 3/16 stock, and I will need to find some calipers, maybe used with new pads. I think I can do the whole thing for around $200 or less, and with the less grinding/cutting on the axle flange, it may be safer in reguard to the strength of the axle flange. We'll find out on my next pay check (next weekend)!

I still haven't found anything for disk break kits for the front axle.
I'm working on that other front spring assembly today.

I just bought brackets from ebay they use Lincoln rotors and cad rear calipers with e-brake built in went to pick a part with a micrometer got almost new rotors 20.00 each calipers 20.00 each and ebay brackets 80.00 turn rotors 10.00 new pads 15.00 =175.00they work great oh I bought caliper rebuild kits for 7.00 each but there still in garage somewhere.....ted
