Is the 1987-88 Tecate 4 rear axle interchangeable with the 1986-87 Tecate 3? If not, how about the Mojave? Will the rear axle on the Mojave work on a 1986-87 Tecate 3? I know that the part numbers are different, but that doesn't necessarily mean the parts aren't interchangeable. Anyone out there with any exposure to this subject? Any help would greatly be appreciated!
