Folks, got a question on frame straightening. Early 30 frame, A280XXXX.

Frame rails are flat, and there is a bit of twist which I can get out by jacking on opposite corners. But the long cross dimension is out by about 1/8”. I’ve tried pulling the corners together but it springs back when I release the tension, so it’s pretty well where it is. I know that the proper thing to do (and what I’m sure Brent would do!) is to drill out the rivets, set it up on a jig and re-rivet. But practically speaking, is 1/8” racking significant? I’ve heard that body shops consider 1/8” to be acceptable. It may be that this discrepancy will lessen when I get the twist out.

Also, to confirm, the frame horns’ outside edge continues straight from the rails behind, right?

Thanks a million.
