It turns out that Spicer unit was an "optional 5 speed transmission (model number correction noted) for the '81 C70 and coupled with the big block engines. I've no idea at the moment what pto drives fit either port on that unit, but if I get a chance later I'll see what info I can dig up. Enjoy your toys!
