TCI front subframe 1967 Firebird

[Crazy Nomad]

Hopefully this is the proper section for this question... Has anyone installed a TCI front subframe in a 1st gen Camaro/Firebird? I am having issues squaring my new TCI subframe to my 67 Firebird. The Car body and the frame measure out square, however when I put it under the car it won't square up. I have a fischer body manual I am using for cross measurements. I then stuck a bolt in the drivers side front mount and used jacks and jack stands to "tighten" the frame to the body and got a good cross measurement and none of the other bolts will go in. I replaced the left and right floor pans so I could have them off a little and understand that and i can easily fix that if its an issue. The front mounting holes not lining up has me concerned. I can't find a center to center measurement for the front factory mounting holes so I cant tell if the TCI clip is off. I have many years experience in a body shop including frame work and this has me scratching my head. Any help, advise, references, or videos would be helpful. Thank you
