Just a follow-up: I looked again and it has leaf springs with a 10-bolt cover like in the pic Lincoln posted, so I guess it's a Dana 60. The "for sale" sign reads V8. If I remember right a 68 may have a 307, 350 or 396, right?
I don't think I will pursue this any further - the truck has more rust than I want to deal with...
Thanks for the info!
