I took my drive shaft with the front and rear ujoints over to my friends shop. We looked at a few different drive shaft and u-joint sizes from a huge stack of them that he has. My u-joints look about like what you would see on a late model 4 cylinder car. My drive shaft also looks like a 4 cylinder car one. Even though my car was an original V8 I guess its possible that I may have wound up somehow with a drive shaft and u joints from a 6 cylinder.

They are going to make me up a setup like their dirt track cars with a bigger drive shaft and solid u joints. I think they used a pickup drive shaft for theirs. He has a balancer for doing drive shafts so I should be ready to go once they get it done.

Good 3" driveline tubing (kinda like DOM 1020) and 1330 series Spicer joints are really all you need...

Even some of my buddies who ran 4 speeds and in the high 10's back in the old days used this stuff...

Most importantly, the drivetrain geometry was aligned correctly and precisely controlled....that's the biggest factor in driveline longevity...

When you start making over 600 hp and launch with the wheels a foot in the air, billet yokes and 4130 tubing and 1350 u-joints become more important....*G*

Hate to say it but I still have the exact same driveline and u-joints that I bought my race car with back in 1979.....everything still looks like new (well, a little dirty right now).....

I'm a little foggy...did you break your u-joints or twist the DS into a pretzel? I take it you've got front and rear safety loops, yes?

I've never twisted it up but who knows what happened to the car before I got it. My u-joints cap to cap are just a nudge over 3 inches. The drive shaft looks a bit shy of 3 inches but only by a little(2 7/8ths?).

Last year I was having some vibration that wound up being the front u-joint. I went down to Napa to get new front and rear u-joints and I asked for solids then. They had them but not in my smaller sizes. The dude down there said then that it looked like I had 6 cylinder car u-joints. I kept the boxes my joints came in. One was a 5-2173 and the other was a 5-2011X. Both have only the inside snap rings. Who knows. I have a front loop on it.

My friend won't charge me a lot to set something up but so far he's having trouble finding an appropriate C4 yoke with the bigger u-joint size for it.

Hey, he can always get a billet yoke from Mark Williams....
Open your wallet widely...*G*

Only thing I could think of would be a C4 in a big car like an old Fairlane or Galaxie....some of the early ones came with 289s and C4's...

Or, maybe a F100 or F150 truck with a small block and C4...they came with 9" rears usually and maybe would have a larger DS and Ujoints...

Sorry I can't help more on that one...

I'll check the dimensions on my extra C4 yoke in the shop and let you know....
