I hope the time will soon come to put the driveshaft back in my '21. I don't have "THE" book yet, but I have one ordered. I've read about peening the driveshaft pin , but have not yet seen a picture. Can someone post a pic of a properly peened pin? Thanks.

Peening the ujoint pin is a double edge sword. If you peen too much it is hard to remove (been there done it!), but if you don't peen enough it might slip out. More experienced guys can chime in.

Put a bolt in the opposite side as a buck & hammer with a punch from other side.

I think bolt is same a rear spring perch hanger bolt.

Tommy,

If you do put in a bolt to buck the pin, be sure that the head of that bolt is resting on something solid. Otherwise, you run the risk of driving the bolt out of the plug hole and stripping the threads.

The fan arm bolt also works as a buck. I pre-pein one end of the pin, slight counter bore in the end of the fan arm bolt, insert pin, insert bolt, flop assembly over & pein away !

Make sure the new pin is the correct size: "PIN Universal joint knuckle, 9/32 x 1-1/2, cold rolled type G steel
2574".
I bought one from one of the vendors that was undersize in the diameter so was not a tight fit.

Do not use a roll pin. It is too hard and if it comes loose it can cut the end of the driveshaft tube off.
