I am midway through a swap of a 1990 into 86.5 The 90 has been through a flood and I am swapping suspension all the way around. I finished the front end and want to use the rear differential and all to replace the rear on the 86. The 90 is turbo and the 86 isn't. Will it mount or what do I need to make it mount. Let me know if more info is needed.
