Did something similar. Took the suspension from a 08 Silverado. Also took the drivetrain. Truck was originally a 2wd with torsion bar suspension now it’s a 4wd with coil overs and a wider stance. Still working on wiring, got it starting up, just need to do the electronic 4wd and tie in wires to the fuse box. One day I’ll make a forum but that’s so much typing😵
