Alright, got a question. I took my crossmember off to bash it in so my 4-1 header would clear and ended up beating it out of wack. (Don't ask how) So are all 88-91 Civic/Crx crossmembers the same. Will a 4 door 88-91 civic crossmember work also? Thanks in Adavance

 

I used a dx crossmember on my rex since the bashing and grinding work to clear the header was already done. I didn't want to mash up the CRX crossmember because i'm gonna save that for my turbo setup. As for the 4 door 88-91 civic I'm not sure about.

 

so they are interchangeable?

 

Yes, they are interchangeable.
