I did similar repair as yours, but definitely not to correct as severe damage as you have. As you progress I would constantly and I mean "constantly" scour "for sale" or "free parts" in the Stovebolt forums or Craigslist. Even EBay as long as it's resonably priced. Doing this I was able to find a frame for less than the cost of straightening mine and inner fenders for next to nothing. Also, as the job progresses, post what you need. I bet a Stovebolter will help you out. And for me at my AARP age, little steps was the way to go so I didn't feel overwhelmed. Still at it too!
