I just installed a repo for the drivers side on my "48" 3100. Very little tweaking and works perfect. Purchased from an e-bay vendor called Classic Chevy Truck Parts. Seller name is chevykens. He stood behind his latch to the point that he would pay the freight to return it if I was not happy. I was happy with the latch.

If you never tell a lie, you never need to remember what you said.
