I've documented the originality of my '50 many time in
discussions here and it was 95% original when I bought it. The
original floor mats were still in it and the floor is solid and
in tack and unmolested also. No stabilizer pins near the seat,
only on the toe board.
It sounds to me like it was common to the GMC but not the
Chevy's and ended with 50.
It would be easy enough to spot weld a couple in Alvin or you
could even punch a 1/4" hole and double nut a machine screw in
place of welding it in.
