Yesterday I tried to install H&R lowering spring on my 2002 legacy GT using KYB struts. I had no problem putting on the rear it was the front I had a problem with. I now know I need part number 20323FA000 which is a new spring seat for the front springs. That is because the H&R springs are more narrow than the OEM springs. My problem is that on http://www.subarugenuineparts.com it come up with 6 different parts. 5 under collision catalogue and 1 under OEM. I am not sure which one I need. Can any one help me?
