I am looking at an '89 HB with a bad engine. I think it is the 1.5 DX model with a 4 speed. I can get a pretty nice '90 Accord EX auto. The trans is bad in that along with body rust. First, can I swap the engine into the HB. Also, what other parts can I use from the Accord? Seats, wheels, A/c system, dash parts, auto shift linkage? I would like to convert the HB either into a 5 speed or automatic. Also, I would like to dress up the HB a little if the parts will interchange. Also, what engines models are in the cars. I see guess that I have to know the codes on each.
