Hey guys, I just installed my #10 tst plate according to the tst website directions. Everything went pretty smoothly and the truck runs great! I left the starwheel and plate in the stock position though. Anyway, after everything was done and I cleaned up my tools, I found a single 10mm crush washer sitting on the ground beneath my truck... It wasn't a lock washer like the ones in the afc housing. Anyone have any idea what it could be from? Does the oil dipstick bolt have a washer on it? I'm thinking it might be from that.
