Do not know what the composition was back then. But living in Pennsylvania, the rust-belt state, I have repaired hundreds of frames. We always used A-36 steel, or what is know as mild, to do the repair. Cut out the rusted area, overlap with the patch at least 1/2 inch beyond cut, and weld in with Lincoln 6010 or 5P 1/8th rod. Only use the same thickness of what the original frame was. This will give it the flexibility as originally built. Anything thicker will cause the frame to crack elsewhere. Most car frames are of a soft steel so as to give and bend but not break.

I've been a guest on Packard info for a few years now. Finally decided to join in but I'm highly computer illiterate. I been lucky enough to have my daughter and a friend help me attempt doing this.
First off I'm the one from Punxsutawney that built Black Bess II. I'm in the process now of building a 57 Detroit style 400. I also have the frame built for the 57 Clipper (not sure yet what body style). Also a 56 Clipper chassis to build my own Predictor.
I stripped out three 56 Packards and four 56 Clippers that were totally gone. I have enough running gears and parts to keep me well supplied with my endeavor. What I'm having trouble on right now is finding the time to work on any one of these. The 57 400 Project hasn't been toughed for a year now. It needs the cowl top, hood, front bumper, grille and front bumper built yet. This will finish the body in white.
I'm up to answer any questions at all on these projects but it may take awhile till I can get computer help.
I've enclosed pictures of Black Bess II, the 57 Packard project, and a life size wall painting that I use to get my body measurements. Thanks for your time.
