I guess I should of said hex bolts. Old habit.
Anyways if you're looking for clutch heads, most of the common ones are available from various vendors, both Chevy parts suppliers and restoration hardware suppliers.
If you're looking for hex bolts with the correct foundry marks, the only place I know of to find them is to take them off original vehicles. On my '51, the majority were marked TR or R on the head. A few had WB and there were a few with no markings. You can usually tell an original nut or bolt from a later replacement, the bolt head or nut is "thicker" than what you'll find at a hardware store today, if that makes any sense. I can't recall the foundries with those markings off the top of my head, perhaps someone will chime in.
If you're just looking for the correct size and length, let me know what you need. I replated and black oxided all my original bolts, and I've got them bagged and ready to start reassembly here as soon as the weather breaks.
