well I've been tryin to find some info on this but soo far... nothing.. soo here goes.. I wanna get new fenders since mines are all busted and dent and what knott.. so I was just gonna get the OEM ones but after looking around I liked Si-R fenders alot since the sidemarker slot is already pre-cut.. So my question is; will the Si-R fenders fit if I still have the USDM front bumper/hood?? or do I need the whole Si-R conversion to put those fenders on my car??
