It finally dawned upon me that what I really need is for someone parting out a 51-55 Kaiser 4 door to saws-all a chunk of the base of the B-pillars (above the bottom hinge for the back doors). These chunks of door frame should be mostly rust-free and suitable for welding. I have found a couple of ads from people who are parting out late model Kaisers, and have texted them to see if they have what I need. If anyone in this forum is parting out a 4 door and has what I need, please let me know. Thanks!
