There's been an H2 frame in Atlanta that keeps popping up on Ebay, the guy claims it was powdercoated for another project then they changed directions. I think it was up for pretty cheap recently, like $1500 rolling.
You could do a frame swap and then check all your parts out as you put it back together---add, mod or change what you want or need along the way along while freshening it all up.
That's not to mention what a PERFECT time for a diesel swap this would be, especially since you've got a an H2 conversion shop in your neck of the woods.
If you lived any closer I'd be pushing you to do the frame swap---I'd even empty out my garage for the project until it was done. I swapped frames on my 77 GMC when I was a teen in the backyard of my mom's house--no concrete or specialized tools, so having a garage and better tools would make this pretty awesome.
Wow, this can awesomely spiral out of control really fast......
