I actually can't even remember the last ime I changed a u-joint, Might have used a bench vise or an arbor press - I just don't remember, but don't think there was any punching through. Put a new driveshaft in the Barracuda over 20 years ago and it came with the u-joint installed. A nieghbor broke that vise doing a u-joint didn't take the clips out IIRC. sigh.
