My friend just bought a "hose kit" for his '88 Jaguar XJ-6, which contains all the hoses needed for his the engine bay. My '84 245GLT's hoses are pretty old, with some dry-rotting/cracking showing on many of the ends. Does anybody know if you can get a kit which contains all the rubber hoses for the engine bay, so you can perhaps save some money over buying them all seperately? In addition, my rear hatch shimmys & squeaks like crazy at highway speeds. When I lower my windows, the squeaking subsides, but it's still there. I took a look at the rubber weather stripping on the hatch door and it's really old, thin, and basically shot. I think the hatch shimmys & squeaks due to the weatehr stripping not creating a good seal when closed. Any opinions and any idea where to get new stripping? I should also note that the wiring running through the rear hatch hinges is severed, which is due to hinge wear. Can the hinges wear to the point where they elongate, thus preventing the rear hatch from closing as closely/tightly to the body as when new? Can this, along with the weather stripping, contribute to the shimmying & squeaking from the rear hatch?
