I replaced all the common hardware on every engine I build, if it's not a special specfic to that engine fastner it goes straight to the scrap steel barrel. I use alot of grade 8 fastners, not because all of the applications need grade 8, but more because they are gold zinc plated rather than white zinc plated and I think they look better. Replacing all the common fastners in a engine even with grade 8 does cost more than 20-30 bucks, and if I attempted clean all crappy NOS hardware, my labor would be way more than that to do it, so the customer gets the good stuff and saves money.
Rut, glad I could help with hooking you and Gordon up, he's a good guy, and not your run of the mill Moss distributor, Gordon is English as you well know now, and has alot of UK connections, and gets stuff you don't find at the run of the mill Moss distributor. Buying from the UK is a tricky deal, they have thier fair share of idiots over there, so knowing who to buy from, and who not to, is key, and Gordon has forgotten more than most of us will ever know about buying from the UK.
