A 904 uses a 26 spline and a 727 uses a 29 spline...
weight of the car will make the big difference BUT
you would most likely be better off with the 7290 joint




The car is a '69 Barracuda notchback with fiberglass front end. Guessing 3100 lbs-ish

I think I will plan for the 7290 u joints. I will head to the junkyard and get a 904 and 8 3/4 yokes for the 7290. May be hard to get the 8 3/4 yoke off at the junkyard though! I can't get the pinion nut off my 70 Sport Satellite 8 3/4 while its in the car.




I don't think you will find a 904 yoke that will take a 7290 u joint!
