Rob...I have the driveshaft out of my 70 Nova[same rear end as yours?] I can crawl under it and measure anything you want on the yoke. let me know what you need.

Tony, If you can measure both the ID between the ears or tabs on the yoke, and the OD of the caps on the u-joint.

John, I also looked at the "girdles" that Moroso makes. Thanks for the info.

The measurement betwee the tabs is 3.220
The measurement, total length of the u joint, cap to cap, is 3.221, so it is a snug fit.
The OD of the cap is 1.065

You are welcome. I hope it helps.

Change the pinion flange. It's common for the little tits that act as the 'stop' to wear and that allows the U-joint caps to move. It only needs to be slightly worn to cause a lot of vibration!! I would change the straps also.

Ditto what PaulK says! The pinion flange on my '69 Yenko Camaro was only slightly worn, but changing it completely did away with my driveline vibration.

Well it looks like the problem is that it is worn bewteen the stops, allowing the movement. The measurement is close to 3 5/16 between the stops.

The caps under rotation got "pushed" to the stops, allowing the side to side movement within the caps.

Would you change the pinion flange or buy the Moroso caps for now.?
