Here’s one way to chop an AD Chevy truck. Not the only way, this is just the way we're doing this one. We don’t want to lean the posts back or have to quarter the roof so, we’re going to use a second roof skin on this one. We start off by cutting the door tops off and tacking them to the cab to keep everything in alignment when we cut the top off. Unfortunately, we don’t have hinges or latches for this cab so this is the quickest way to keep everything where it belongs. A couple of pieces of tubing welded inside also help keep it square. We started off by marking the cab with all of our planned cuts. The plan is to take about ¼” more out of the front than the back. Bringing down each of the six pillars individually will allow us to maintain the angles of each pillar. Because of the taper of the pillars this leaves the hole where the removed top is bigger than the piece we cut out when it is 3 ½ inches lower so the spare roof is cut to fit the new lower, larger hole. Once the top is tacked back in place there are a few areas that have to be pieced back together and patched using parts of the pillars that were removed for patch material. Finally the door tops were cut and fitted back in place. Unfortunately, we don’t get to see the truck completed right now. We chopped this cab for another shop in town that is building the truck.
