Right, but I think I heard that they were bought out by someone 
else a few years ago. Still, they would be my first choice.

Okay, that sounds right. I've always been distrustful of the 
construction of this part. I ALWAYS take the shaft out and have 
the weld improved. All the shafts I have seen, including originals, 
have a weld on the "pushing" side and none on the "pulling" side. I 
get a friendly welder to add a nice bead to the pulling side also; I 
just think this reduces the chances of peeling the arms off the 
shaft, which apparently happened to you. While most of them 
seem to last a long time, I have always taken advantage of any 
opportunity to beef it up. I think this would be essential for anyone 
planning to upgrade to a stronger than stock pressure plate.

I worry about loose springs, too, and I have seen disks with broken 
springs. I often inspect pressure plates, emery down the surface, 
and reuse them. 

Did you notice which brand of pressure plate your 63 had? 
Sometimes there is a date code stamped on them so you can tell 
if it was the original. I assume it was one of the old style 180mm 
with 6 or 9 springs. Do they make a 180mm diaphram pressure 
plate now?
