i have a huge stash of factory nuts, bolts, and screws i keep when i take these cars apart, i have a nut and bolt bin with about 40 trays in it!! what are you looking for specifically?
no offense but you are that crazy about those bolts you mentioned? why not bolt a bench grinder to a work bench and get a wire wheel if you want the new stock look? thats all i use if i'm cleaning threads and bolt heads, if you want that original look thats your cheapest and best bet.
im not crazy about them. i u sually replace hardware when i replace a part. dunno why im just ocd. come to thing of it though i do have the stuff to do the wire wheel job but its really not too important, i was just curoius. i guess i might if i have them off again later, but i dont plan on it
