Currently swapping wimpy 04 WRX front knuckle and bearings for 05-07 STi ones. Did not realize the holes for my current Quantum Motorsports duct plates do not fit on the newer year knuckles. Surprise - The 05-07 plates are now discontinued from LIC and Quantum has gone rogue.
Time to bust out the welder? To McMaster Carr, and the 3D printer first!
