<VV> LM Rear Axle:Caps and races different lengths on same U-joint?

[Jim Davis]

Half-shaft are the same length.  65 yokes use 1"-28 grade 8 cap screws 
and straps to anchor the universal's caps.   66-9 use 5/16-24 grade 8 
washer head cap screws and slightly different straps to anchor the 
universal's caps.  All Corvair universal joints are 1310 size (3.129" 
width and 1.062" cap diameter).  The heavy duty U-joints have smaller 
diameter and longer needle bearings.   Best to attach the rear 
suspension and drive shafts with the drive train about 6" lower than its 
installed position this eliminates the angle of the bolts in the strut 
rods and allows the best guess to toe-in setting. Sometimes it is 
necessary to use a "come-a-long" around the shock mounting points on the 
trailing arms to overcome the splay caused heavy duty springs, but 
usually this is not necessary with stock springs.
