I have a 1990 Civic LX sedan and I'm looking to fit a front bumper assembly from a 90 CRX and was curious if anyone on here has seen or done this. If anyone has any information that could help me out I would appreciate it. Thanks.

it could be done, but its not a bolt up plug and play affair. easiest way would be to bring the crx bumper to a shop and see what they say.

well I've seen a 6th gen. civic bumper on the back of a crx before, but I haven't seen any of what you want.

i hope they plan to fill that gap between the lights and bumper. but a cool idea.
