Drive Shaft ?

X2 on the 1350 Spicers....as you said, you will more than likely have to replace both the trans slip yoke and the pinion yoke.

Also, just a plug for some others here on the board...I have read that there are some that are running 7290's with no problems and in the 10 second quarter range. Just depends on what you are going to do with your car now and later down the road.
