Cab forward is done. But we found an issue with the rear axle assembly. First it has 2.56 gear set in it and in 4th gear (overdrive) it will run 1,400 rpm at 70MPH. This is a 10 bolt 8.5 out of a 1984 Chevy Silverado so that should explain the gear set. Take off and acceleration will be sluggish. Second the spider gears are toast so either a rebuild is in order or find a donor. We decided on either 3.73 gears which is 70 MPH @ 2200RPM or 3.55 gears that will be 1,900 there abouts @70MPH. My dad said he wants to finish up the rear axle and replace the shocks before installing the bed
