How to Check Uni body for Straightness
I am working on repairing and stiffening my '69 Barracuda front frame rails and torsion bar cross-member. At one point in her life someone cut holes in the torsion bar cross member to install fender-well headers.

They also cut out this sheet metal piece below the firewall, that connects rockers to the frame rail.

There is also some rust in a 10" section of the front frame rail right in front of the torsion bar cross-member.

Before stiffening these areas I want to make sure that everything is relatively straight. I have her on 4 jack stands two on the frame rails in front of the K frame. Then two in front of the rear spring mount on the rear frame rail.
I know the floor in my garage isn't totally flat or level. Laid a 4' level on the floor and there is a bit of a crown to the floor under the car. I have never driven the car so I don't know if it runs straight or has any real issues. I am a bit concerned about it potentially having some twist because it has a 440 in it combined with the holes cut for fender well headers.
Any suggestions on leveling her out and checking to she if shes square and straight?
