Anybody have a good source for information on the changes through the years of the Impreza? I'm wondering little things like is the bolt pattern on the wheels the same all the way through? Will parts for the RS fit on the earlier L sedan? Such as exterior and interior, not so much engine parts as mine is just a 1.8 and the RS was the 2.2 and 2.5 I think.

Thanx
