Custom Lower Radiator Supports for sale

I think that it would be a good idea to tie the front frame rails together. I would get the car on a level floor on jack stands supported by the frame rails and start comparing measurements to the floor side to side. What if it's not level in the front end are you going to cut one of your bars?

John/others - I'm currently preparing to install the lower radiator support and decided to check side-to-side vertical position of front subframe rails relative to the rear subframe rails on my '65 Barracuda. I'm using a level to establish the relation and am seeing a difference of roughly 0.28 inch as measured at the rear. In other words, with the front rails set to level, I see approximately 0.28 inch off level at the rear rails.

I know these old cars are not precise. My car already has welded subframe connectors and an 8-point rollbar. The door gaps are consistent and there is no visible evidence of body twist. Knowing that no car is perfect in this regard, at what tolerance would you judge it is still OK? I am stuck on this and can't seem to get off of it. Thanks.
