Went and looked at the 73 'cuda, thanks again to everyone for the help decoding and etc.
The cuda has a rusted trunk floor, and frt and rear floor pans both sides, and its pretty extensive. The floors dont scare me too much, but the frame kinda does. The rear portion of the rear frame rails are rusted approx 8" in length, most of it all the way thru. Is this repairable with new sections? Are they available or are they a custom make??? The other question I have is the 1/4s were replaced years ago, and still look good, but the wheel houses are not welded to the 1/4s, I guess a patch could be welded between the 1/4s and the wheel houses, or not....thats why Im here, Im no expert!
