The honest answer is my work was ok, I spent an whole lot of time and money getting it to this stage. Now that I am in the Bronco world more and more I hear the secrets. I met up with Mark with San Diego Broncos, a long time builder and A plus fix it man told me the parts coming from the various metal stampers are way off, there are so many tweaks needed that most of us are unaware of, the big ones are the cowl, it needs allot of tweaking, it is not correct so if you are building an entire body around it everything will be off. Most of the big builders have their metal reworked before installation. If you notice on some of the new tub makers there are larger gaps at the window frame door, that is from poor stamping, not fabricator error. The reason I love this site is great insight, I hope this helps the next person. FYI this an exceptional issue since I built an entire new tub..
