I was told that the chassis was built in a Nascar fab shop,whoever built the chassis was an amazing fabricator. Everything is tig welded, but unfortunately one of the previous owners was trying to turn it into a Fast and Furious wannabe and they butchered the fenders,doors and hood. They also cut and distorted the rear window plug trying to put flush glass in the car. I will probably have to cut the rear window plug out and build a new one. Who ever did this was not the same person who built the chassis. I have been undoing all of the hack work that was done by this guy. He made the hood so that there is one large depression instead of two like the factory Charger hood. He gaffed the fenders and doors up by cutting and welding all over them with no rhyme or reason.
