I had my R/T in the shop changing the rear spring bushings out and to find some water leaks in the driver's side floor. There were a couple spots on the top of the door seal as well as the high mount stop light. I'm assuming the foam gasket is all that seals the high mount stop light from getting water inside the cab. I don't want to buy one of the cheap LED roof lights but the few NOS ones around are well over $100. I don't see one from Dorman. It doesn't appear the gasket is available separate. Is there any other options?
