Thanks, I'll look closer for any numbers on the disc. The other side is really lathered up in yellow paint.Don't know about the pressure plate. But the clutch disc appears to be a Scheifer, they painted their stuff that bright rich yellow. They were good stuff, they went out of business in the mid 70's-the owner died. I have the Scheifer part numbers-so if you can find a number anywhere on the disc, I can identify it. Weber also painted their stuff yellow.
Is Perfection HyTest a decent brand? I've never heard of them.As said the disc looks to be Scheifer, The clutch diaphragm cover is made by Perfection HyTest company. Looks to be used on 69 383 with 11 inch.
No idea. https://www.perfectionclutch.com/Is Perfection HyTest a decent brand? I've never heard of them.
At this point I do not think anything matters. It is just a usable 11 inch 18 spline disc.
