To get the old one out, use a hack saw and make a notch in the "screw" and then use a flat head screw driver to take it out. Works like a charm. And you can use any TSP from any honda from 88 on up, but the 88-91 civic dx will have to have 2 wires swapped, as well as the 88-89 prelude for sure. Maybe the 90-91 ludes too. But any other civic, and teg, etc will work. If you end up not fiding one, I might be able to hook you up. Gotta see what's in the old garage.
