Not knowing where you are but would say I do have the crankcases for the 1972 you see over to the left. I'm near Syracuse NY.
I would have to look them over to know if there was any obvious problems with them. One thing I know if that bike was stored in a leaking shed for many years so the outside of the cases would need some serious cleaning.
Pretty sure I do have the frame from that bike still out in the barn, not sure if I checked to see if numbers matched. One thing I know I don't have is the title. Bike was last licensed in 1984 in Oregon going by tag on the plate. Forget when I obtained it but was sometime between 2000 and 2010 so I would say it spent around 20 years in that shed!
If there is any interest I could drag them out and give a quick look over and maybe take some pictures. Price would be very negotiable. If shipping was involved I would need to get shipping costs plus enough to cover my time and effort plus a little to encourage get my but moving.
Just to give an idea of how bad it was I'm attaching a right side view of engine before I started dismantling to sell parts.
