New Clutch.....Problems

McLeod was red for as long as I can remember (1979) and I don't remember who was yellow. Back in the day...the DC clutch was green. It's possible that PP was rebuilt by someone who planted it their color.

I agree with RC69. Have the PP you already have rebuilt and use a new disc and be done.
Just remember as the disc wears the finger height moves closer to the throw out bearing. So...the thinner the disc, the higher the finger height.
I tried looking up mccleod, and I think they just do diaphragm covers, now. I tried looking up weber, and from what I could gather, all they make are cams, now. I'd suggest finding the nearest reputable rebuilder to rebuild your old one. Someone here on FABO, can probably recommend one near you.
