The car does not matter as long as you have the harness and components you are going to run the you should have no issues. Pending the car had no issues when you buy it.
and as you know the OBD1 components are not the same sas OBD2
Some of the problems i have ran into in the past is running a auto harness and 5 sp car. It didn't work. but i didn't do my homework. now i now better. It only takes once to figure out.
Good luck with the build
