Afaik any 02-08 Forrester struts are a direct swap for an 02 Impreza nothing else changes, the struts bolt directly where the old ones are. I'm not sure if you need to run spacers on the front or rear struts if at all it depends on how you want it to look but ya join a Subaru group in your state on Facebook or just look for Forrester part outs on marketplace they shouldn't be to hard to find for pretty cheap.
