I did get everything tack'ed up and then did some more substantial welds. being careful to not get any part too hot and jumped around quite a bit. after re-fitting after that... no real issues she lines back up. yea! now I will drop it or something and tweak, yea probably.
I still need to do the front seams but after some more welds and a couple more grinder parties she should be ready for final blasting and a couple coat of epoxy.
