Does anyone know of or are running headers in an obs 4x4? I know you can find them for the 2wd but ive looked and looked and for the life of me cant find any for 4wd. I know the obs has tighter frame rails so i dont think headers for newer 4wd will work. Anybody fabbed there own? swappin in a 6.0 andlike to get as much out of the way as possible. trucks a 92 rcsb 4wd.
