On the new truck they are LONGER. i have seen on the older truck SHORTER, all rubber, i don't know who is making them, i got mine from VAN'S auto , they are the short one's for a 1978
There's an upper and lower "bumper". The lowers hold the hinges and the uppers stop the top of the tailgate from rattling. As I wrote in the opening of my thread I have a '79. Here's the LMC page with diagram of what they refer to "upper" and "lower" numbers 11 and 12. I was in need of number 11 the round uppers
