Some Basic Chassis Repair Work On Our Road Race Thunderbird

When the T Bird arrived in our shop, we knew she was in need of a little special attention.  The wounded chiicken was fresth from a "slide and bounce", off one of the Road America guard rails, which drove the right rear tire into the frame.  This former ASA race car is well built, but there was no choice except to replace the section of damaged frame that had been bent.  In the photo below, you can see where we took a Sazall, and a set of torches, to remove the bent  piece of 2" x 3" mild steel.  There are also a couple of welds that cracked in the crash, and we will deal with them at the tail end of the process.  Right now, our job is to set about fabricated a direct replacement frame unit, based on some simple measurements that were taken in the shop.  The right side mounted remote oil tank had to be removed, for the work to start, and is not present in the photos.
