here is the post that has the most info that i found and plus what i got from doing the research on this topic.
Well here is what I found after talking to the Subaru dealer here in VA. I got all the parts need to do and the prices.
03 to 04 Front end swap
Headlamp assembly 250.00 ea 500.00
Front fenders 136.00 ea 272.00
Front Bumper assembly 436.00
(Includes: Front bumper cover, Bumper bar, Bumper absorber)
Fog light covers 112.00 ea 224.00
Radiator Support 212.00
(Upper & lower bars, side bars, and hood latch)
Hood w/scoop 500.00
That is with our local NASIOC discount. Plus it all has to get painted. I hope this help anybodie looking into doing this.
