If it's not one thing it's another!!!!

Can't get my nut on the bolt of the drive shaft to re attach the universal yoke... either it's got stripped on the process or it was like that before. Don't really wanna grind it down, the tip of the bolt is stripped so I can't get the nut on or started.

 

You mushed when you were using the puller. It won't hurt anything to slightly bevel the edge. Grinding it down is your only choice.

 

Get a 2 piece dye. Put it on and heat the shit out of it with an acetalyne torch and cut some new threads

 

It looks like you put a puller on that shaft and mushroomed those threads

 

I would suggest trying to get a correct sized die to start on it.

 

Ya I'm gonna get the right size die and see if that works, I think it will clean it up no problem, in just stuck and have to walk across town

 

I had to heft my drive shaft across town once... guess it's good for this old man to walk once in a while...

 

Try using a thread file. They are life savers and cheap
