I looked at a few figures on the FAM to try and cross over the PN's to the size on the link, but unfortunately, none of the bolt PN's that I tried matched what was on the parts list.

You can, however successfully cross the nut PN's to sizes, and at least find the diameter and pitch of the corresponding bolt. The parts list also doesn't include any clutch head fasteners, such as the flat head ones I found at the outside ends of the hood brace rods. The
Master Parts Catalog does have a parts history section that lists supercessions, but that's too much cross-referencing to be worthwhile (at least to me).
Mike B's Classic Parts link is pretty spendy, but you'd expect that for the time they took to catalog and package everything. Stainless steel is overkill, IMO.
