John,

Would you please contact me if you find a source for the set attachment hardware? I need one set (for one connection point).

The Chevy screws are called "clutch head" and divers are available from NAPA (we have been told) and most reproduction parts vendors.

Chev's of the 40's use to sell a set of driver bits that are quite useful with a small ratchet or driver (they also sell a 1/4" socket for the bits/tips).
