87 MkIII vs 89MkIII -- parts interchange

Well I know that injectors and coil packs are inter-changeable but the NA cars do not have coil packs, they have a coil but thats it, the wire harness and ECU's are not compatible, unless the harness has been re-pinned but I haven't heard to much of that. I would say the harness and ECU are just about the biggest differences, and to my knowledge all mechanical components are identical such as heads and blocks. The trannys are the same, W58. I think the rears have the same ratios but I could be wrong, and they are inter-changeable as well.
As for the exterior components, they are all interchangeable as well. Hope this helped.
