Will front 97 Legacy GT Sedan struts work on 97 Impreza OBS? will the ride height be okay?

Hm.....upper spring seat sizes are sure to be different, so if it works I would guess you would need to run the Legacy springs and Legacy upper spring seats together, or the Forester upper spring seats and Forester springs together.

 

Can do some part # checks and such if desired....

okay i've never disassembled the struts before.

 

i thought for sure that any EJ strut could be used in an XT6 if you swapped the top strut mount. so i was figuring at most i could swap the top strut mount and use these Legacy struts and springs on my impreza. actually i was thinking it would be a straight up swap, didn't know they were that different.

 

i didn't know this was uknown territory, maybe the XT6 guys actually know more since we're the ones playing with EJ struts all the time.

It might not be to others, but I don't know much about doing it.
