Bought the engine for $200. Couldn't pass it up, besides, I over-revved the engine in it now. I have a COMPLETE wiring harness (goes all the way to the gauge cluster). I need a tranny, but should I get a 4th gen or 5th gen D-series tranny, because the tranny mounts are so different. Can't I save headache and money by getting the 4th gen tranny? Also, which axles do I use, or does that depend on the tranny i use?
