I am in the process of replacing the full floors in SWMBO's 65 Fastback, pass side doen. While doing the drivers side found the front floor support was rotted out. After removing the front floor support to replace it I found the lower rear inside & bottom sections of the frame need attention. Using my cut off wheel I cut out the rotted section of the frame & made a replacement section & welded it in yesterday. On Sunday I will grind the welds done & test fit the front floor support. Also found the drivers side rear torque box section is rotted pretty badly & will probably be in need of sectioning in the front portion of the rear frame rail. New pics should be up on my web site in the next couple of days.
