I do not remember the number but it was an adapter unit that had both Chevy and Ford ends. I got mine at the local machine shop.

If my memory is correct the precession part number is 449 for the rear combination joint

The u-joint you need depends upon the yoke. There are two different yokes. Measure your yoke or take it to the parts house. One is a chevy ford cross. I think the other is standard chevy. Most driveshafts will have the same size u-joint on them.

The one I ran is a Napa #369.

The afco part # is a 02560130.

I felt the AFCO joint held up better.

we've had the best luck running the NAPA presision one's though have never ran the afco. one important note, use quality U-bolts, not the ones off the HELP isle at budget auto parts and DO NOT OVERTIGHTEN!! went through this last year. if you have a joint start to go bad and the needles are ground short (on the yoke caps only) overtighting the u-bolts is your problem. kind of off topic but might help someone not lose a shaft, been there, done that.

Get the Moroso girdle caps, tighten them up and maintain an evengap on each side. Not to tight, tightening u-joint girdles to tight is a bigger problem then you think.

Been using the ones off the help section for years with no problems. You can use the moroso girdles but if your rearend moves around a lot they'll hit the driveshaft.

We normally use precision U joints U bolts and have no problems.
