Khanh, when i brought the car to Wicked to have them check it out prior to purchase, im 90% sure i remember them telling me it was an 05. Tom read the serial number off the transmission. i thought the WRX axles had the taper on the end, but now im thinking otherwise and that i may have been misinformed. either way, i can see where the axle connects with the transmission and there is no taper.
@ Wicked, im not sure if you remember my car, it was 2 years ago. haha but im almost positive it is an 05.
