Default Part#s for a 71 Vette

Solid Spicer SPL25-1X U-Joints for Drive Shaft
Solid Spicer SPL30-1X U-Joints for Half-Shafts

These are Spicer Life Solid U-Joints. Call a local drive-shaft shop they should have them in stock and have them install, can save you time and prevent you from damaging the flanges and yokes. Don't ask me how I know. My local shop only charged $7.50 per u-joint to swap out.

The Spicer #'s I have are 5-799x for the 1/2 shafts, the Driveshaft could be 1 of 2 sizes.

5-790x is for the early automatics and 75+ 4 spds.

5-785x is for the early 4 spds. It is smaller then the 790x.


Here's a picture of the tool I make too.

I think there are new new cross reference numbers for Spicer Life solid U-joints.

SPL 22-1X for old 1310 (used on early shark and C2 drive shafts)

SPL 25-1X for old 1330 (used on later 71 on I believe drive shafts)

SPL 30-1X for old 1350 (used for half shafts)

thanks for all the replies, Gary, does that tool just keep the flange from twisting?

Yes it holds the flange secure so it doesn't bend if you press them on/off.
