The DC mounts wouldnt fit in your car, different dimensions.

They would have used stock mounts for your car, there's no reason NOT to...since it came with that engine. Buy an axle for a 90-93 (pick a year) integra, with or without ABS and that will fit. 2 inches would put your engine or transmission straight into the fender wells, so its not off by that much. Im betting its the driver side axle. I have seen one that was about 2 inches too short as well, it was in a pile of used axles we had. Never could figure out wtf it was from, but they do exist.
