First time poster here. I recently purchased a 61 Apache and have learned that the threads that hold the steering wheel in place are stripped. Others have suggested replacing the shaft versus trying to have it repaired. I'm still searching for a replacement shaft, but I'm not having much luck. Borgeson has some that fit 55-57 cars and I'm wondering if they are interchangeable? I disassembled my upper shaft from the intermediate shaft. Is the "knuckle" on the lower end of the steering shaft that fits in the coupler of the intermediate shaft removable? I'll try and post a pic - thanks.
