1964 Valiant "Get Runnin & Drivin"

Mine still moves a VERY slight amount. So, when I put her down for the disc brakes, I'll be doing some reinforcement to the K frame too. You do know there's a factory reinforcement bracket to fix your problem, right? I actually have one to go on my rat truck.....IF I ever finish it. lol
Yep...it has a brace on it already. I did like you, and got my wife to turn the wheel while I eyeballed it. Chunk of the frame flexes back and forth. I plan on downing it this winter and fixing it. I have a good running, low mile 5.9 Magnum with all the wiring and computer to install, so I'll fix the frame and get the steering box to sit still while I have it apart and have some room to work.
