Back Up Light To Body Gaskets for 1965-1966 Mustangs.
Keep a nice seal with new gaskets so moisture can't penetrate your new lights. These gaskets are essential to replace when installing new back up light assembly's. They mount between the back up light body and the rear valance.
Gaskets were the right shape, but the lip that snugs onto the housing is thinner and shallower so it was hard to get them to latch on as well as the stock gaskets.
