my friends got a 1990 CRX Hf will the fender and doors from an 88 89 bolt up and work

 

yes, they should work. The only problem i had with matching different year body parts with the crx is the hood. I used a 91 crx hood on a 88 and it had problems keeping closed. So, i think the latch attachment might be different betwen the years, but for your question you shouldn't have a problem.

 

yes the doors will fit, some times the seatbelt lights come on when swapping doors so make sure you use all parts off old door, and dont listen to JDMLOSER the hoods are exactly the same his car must have been jacked or something
