Sorry thats what I meant by rear differential member. Since the newer STI/WRX is based on the Legacy, I was wondering if I could get a used one instead of a new spec b one....Both are aluminum and both are supporting an R180.
I'm having a friend measure the distance between the mount on his 13 WRX to see if its the same size as mine. Since I'm on a budget I'd much rather spend $30 on a used STI one rather than $130 on a new spec b mount since its a non-essential part. Thoughts?
