Just my $.02 worth, I'll agree with Dennys28, but add that the disc does have some wear displayed by the thickness of disc facings. The rearward facing of the disc looks more worn than the front IMO.

The original specs on the clutch facings (2) are listed as between .137 - .143 inches thick (each) when new per the 1952 Chevy Truck Data PDF (screenshot of the clutch info below).
