"Totally Stainless" sells complete packs for engine and body detailing in 3 styles of bolt and screw heads.Prices range to over $200 for a complete body kit down to $20-$30 for an engine kit. There are many "Totally Stainless" jobbers on EBay that undercut their prices a little, but make it up on shipping.Their kits are also sold by many aftermarket catalog dealers.If you're in the area of Gettysburg,PA, although they are not actually in GBurg proper,you can pick up a pre-order and save shipping.Not sure, but I think Langdons are from them also.
