    4x4 OBS headers.

    You guys that swapped LS's into your 4x4 OBS trucks, what are you using for headers? Trucks not lifted at all, will be using dirty dingo mounts.

    I did the pacesetters too. I have a 4x4 94 6.0 with 4l80. As far as I know these r the best fit. The drivers side will just barely clear the frame either u can let it rub or ping it with a hammer or tie a ratchet strap around it and the pass frame rail and suck it away. For the pass side header it might hit the inspection plate ear on the tranny and that can easily b trimmed off

    Bringing this one back from the dead. Did you guys run your dirty dingo mounts all the way forward? I did and kept my trans mount in the factory position and driveshaft the same length. I'm wondering if I screwed myself for fitting long tubes now.
