check out our instagram for where we cut ours. We wanted to enlarge the door. so we cut right through the middle. we used some heavy angle iron and box tube to rebuild the frame. youll need a welder. it really was not that hard. we cut the back door and stretched in as well. Too keep the door square/ flat... we tacked the extension pieces in. Then hung the door off the original hinges. then we adjusted our pieces of box tube and got it aligned in the frame nice. Once we were happy we welded the extensions in. then skinned over the outside. the inside is still open. we plan on spray foaming it. then re skinning.
Ill grab a picture of how it came out tonight
