Came up with a pretty crude method of straightening the frame, but the results are measuring good. The front wheel sat about 2" to the right before due to the neck being twisted. Frame was welded to the welding table, with a center line drawn on the table. The 3 long arced wires are welded to the neck and hold a reference pointer showing where the center of front tire would be. The wrench at the far right of the pic tightens a nut on the threaded rod. Threaded rod is welded to the chain and pulls on the prybar that drops through the neck. Reinstalled the front end after, and it is centered as well as I can measure.
