727 Question

Thanks all
I worked the problem out it has a regular 727 with a regular yolk and no break mounted. I just took the drive shaft to a shop and had it cut. Went to napa and bought a u joint that was 2 different sizes. The rearend is a 8 3/4, the shaft was for a old 7 1/4 but it all worked out fine. the u joint number if anyone ever needs to mate these two odd sizes is a presicision #308 The two sizes are 2 1/8" and 2 5/8" with 1" cups on both sizes.
Thanks for the info guys.
