I have a crx mk2 heater control unit sitting about. It's in great condition. NOT cracks anywhere, the strip along the bottom is still perfect, there are no cracks around the screw holes at all. the only thing is the little clip that holds in one of the cables has broken but you can take that bit off your heater as it unscrews. I have pictures of it taken with my phone. Let me know if anyone wants to see it. Since this is Honda swap, I thought it'd be nice to do a trade for something. I have a b16b crx and tbh have done a lot to it. Things I'm after now would be a nice steering wheel and boss, a mugen b16 valve cover, anything nice for fishing, just what have you? Let me know, I might well be interested. Or, if you really want it, just make an offer. No lowballers though as I know what it's worth, especially as it's the best heater I've ever seen.
