USPS doing their part to eliminate old Mopar parts

I bet they didnt lose it. It prob ended up in somebody else's garage. How the **** do you lose something like that. Best way to ship one of those is in a spackle bucket, padded real well with the lid screwed in place with dry wall screws and duct tape wrapped around the lid over em.
I shipped many of third members in chlorine buckets with a round piece of 3/4” plywood in the bottom packed tight and a screw lid. Even one to Norway and one to Australia. I’m sure someone along the way stole it.
