8 3/4 rear sure grip with 323 ratio what`s it worth?

Getting a C-body driveshaft cut down today has the big u-joints on both ends. Everything measures out will work great!!

Another option is get a driveshaft made, if you need a different length. It's actually not too expensive.

That's what I would do. All new , no rust issues or bent to deal with.

I agree as well   for what its worth,    you can beef up your drive shaft  and go lighter, they can easily cut of the ends from your existing shafts   or just get original ones  cut up also  drive shaft shops are pretty  cool people,
   If your not to far out of the way  they will come  and measure  everything up  as well  for you
