Looking good so far! I used the similar rears on Devils Cut, they work great. They give the truck the attitude your cab possess. I like the turbo idea, big and nasty For the frame, take a look at the one I built, using channel instead of tube, might help get the frame ideas rolling. Have you decided on a suspension yet? Pissed off had 1/4 elipticals on the rear, and a custom torsion bar on the front, the tube hidden under the radiator. I always liked the huge axle hanging out front..it's a big truck gotta keep that vibe!! Watch your tranny choice, mine was off the 359, and caused fit issues inside for the tranny tunnel Looking forward to your build, Jeff
