This is a stainless steel stud and nut kit for the 348-409 Chevy engines using a steel or an aluminum oil pan. Included in the kit are 20 studs, 20 flange nuts, and 20 washers to protect your oil pan. These are great for keeping that oil pan gasket in place.
LET US KNOW IF YOU HAVE AN ALUMINUM PAN WITH YOUR PAYMENT SO WE SEND LONGER BOLTS. IF WE DON’T HEAR FROM YOU, WE WILL SEND FOR SHEET METAL.
