i'd have to measure to give you the right dimensions and i'm sure someone else will give ya that. just wanted to suggest that when you change it to use non greasable kind. they're a little stronger.
Thanks. I'm building a rear end for a '91 Syclone and I can't measure the u joint. I need to be sure that I have the correct yoke on the rear end, so I need to know what the measurements are for the u joint.
