Uni-joint tool





I forgot to take measurements of the half shaft flange sizes so i can make a holding fixture to press in the new joints when (if) I do my diff swap.
The existing joints felt fine when I had a feel of them, no noise or roughness in their movement, so they were left for now.
So can somebody please measure the following dimensions for me?
Bolt hole spacing -
Bolt hole diameter (yes i know it's 3/8"unf bolt, but clearance size) -
Diameter of main ring -
Yes i could buy something and ship it down here, but the weight makes it not an option....
and besides, I have access to lathes n mills in my job as toolmaker, could knock it up in my lunch break.
I found a 3D model online long time ago, but don't trust the sizes as the spindle mount model was wrong, bolt holes not correct.
The clearance counter-bore was 2.770" (2.750 would be fine) dia, .125 deep (.100 would be fine)
It uses 7/16 bolts, or at least mine does

had a brain fade on the bolt sizes, don't know what made me think they were 3/8".....





must have read it on one of Gary's many posts about using a jig to stop them bending.
I'll end up using 10mm which is 20thou bigger than 3/8" and 40thou smaller than the 7/16" bolt, perfect place to be.
I like to have any tools and needed jigs ready to go when i start a job so i'm not getting held up and waiting around.
Thanks Gary for confirming my sanity is still there.
