My 68 has what I believe to be a Dana60 rear (photo below) and I was going to ask if there is a way to know if the shoes are 12x2 or 12x2.5 without opening things up. The more I read, the less it seems possible until you take it apart.
With that said, I am about to place an order from Rock Auto (screenshot below) and hope I ordered the right parts ; )
