if you have a drive shaft and need it cut or a new tube put in then any machine shop should able to do it. get one thats to long and cut it yourself.

I don't have a drive shaft at all.
I thought a specialty shop had to do it because of the machine
req'd to spin the shaft for checking balance.
I have access to a machine shop, but they don't do automotive
stuff so they certainly wouldn't have a machine to balance it.

As long as they understand phasing and have the equipment to balance it properly.

Any town of a decent size should have a driveline shop that can modify or make a shaft to fit your needs. Check with a local truck repair facility they usually have a handle on who's capable.

I'll investigate that.
thanks

denny's was one of the first I came across when I searched.
I downloaded their measuring instructions.
I was going to go with them, just wanted to see if anyone had any strong opinions about suppliers.

You may find balancing is not required.

I pulled a balanced driveshaft out of my roadster due to a 9" diff swap and the pinion was 1" shorter on the 3.70 that went in than was the pinion on the 2.75 that came out.

The local speed shop built a new driveshaft for me and when I mentioned I was taking it to the balance shop, they told me to give it a try as was since they'd built more than a few driveshafts for 150 mph doorslammers that were not balanced and no problems reported with them.

The new shaft turned out to be very true and smooth running.
Never did balance it.

speaking of balancing, I just got a quote from a local shop, they said they can high speed balance for an extra charge. The guy said he didn't think it was necessary because they check the runout before welding and make sure it is less than .005.
Do you guys think I should spend some extra money getting the balance, considering it is gonna be a street car and no racing?

if the machine shop do their job right you dont need it. im talking for the st. look at the small amount of weight thats on most shafts, less than a oz. at the most.

I hope they check the runout AFTER welding also. The heat can cause distortion. It's not hard to fix runout after welding by selective application of the ol' blue-tip wrench.

I have a blue tip wrench.
I spilled some paint on one of my craftsman's.
The paint happened to be blue.
It'll take a lot of whacks with that sucker to straighten a bent
shaft, but I'm up to it.
