So I asked this question on my build thread but nobody bothered to answer. Thought I'd just throw it out there this way.

Does anyone know if the rear suspension components are completely interchangeable between hatches, sedans and CRXs from 88-91? Specifically the rear upper control arms and the rear toe arms. Are they all of the same dimensions? Did the 1990 facelift change anything?

I'm getting ready to completely overhaul the suspension on my '90 Si hatch, and since I'm getting new bushings for everything back there, it would be convenient to grab new UCAs and toe/component arms from a junkyard EF to install the bushings into, therefore making the overhaul more of a swap-out. However, all the local junkyards have a dozen or so sedans and a couple CRXs, all from before and after the facelift. There are ZERO hatches in the junkyards, meaning that I can't even yank those parts and match them up with other cars to check. I'd like to know if those cars' suspension arms will work for my hatch without throwing my alignment off.

For the record, I did a fair bit of searching around other forums but I haven't stumbled across a solid, concrete answer to this particular issue. I figured one of you older EF-heads would know something about it.

Thanks everybody.

 

Rear upper conrol arms and toe adjusters have the same part number... so yes, they are the same reguardless of what model it came from.

 

That makes a lot of sense, I don't know why I didn't go look that up...

Thanks a lot, man, that's gonna save me a ton of time.

 

New to the forum and I'm having a tough time finding stuff about ef/sedan/crx interchangeability in general, I'd start the thread if I wasn't a trial user, still waiting approval. I have so many questions.....

 

disregard, found what I was looking for, but I still think a general trim interchangeability thread would rock

 

Theres a faq at the top of the forum for newbies like you.
