Well, this happened in a way that I was not planning this morning. I thought I was coming by the shop at 9am to check on progress, but as it turned out, I was there to do the bulk of the work myself. "You didn't think you were coming here to watch us work on YOUR gun, did ya?"
So with the exception of filling the old rivet holes with weld (I suck at welding, especially sheet metal), I got to use their tools and equipment to do the swap myself. They showed me the same hospitality with my Polish underfolder kit, so I am extremely thankful to these folks just for welcoming me into their shop not once, but twice now. They asked the olden days surplus price for the parts, lent me their tools, and we went out to eat afterward. Given the circumstances, I'm just happy to have a fixed stock on my M92 PAP and will get to the cosmetic portion at a later time. Need to do some fitting work on the hardwood stock (anybody know which country it's from?) I ended up picking from the stash, and of course the metal will need to be smoothed out and refinished. But here she is for now.
ETA: Stayed up and finished her.
