What type of U joint should I use when I switch the eaton rear end with a 14 bolt?

Also, did the NP208 ever come with a fixed yoke, because the transfer case in the truck (my friend's 1969 K20 with a 292 and a 4 speed) is a fixed yoke?

If its not an NP208 what is it, NP205 203?

Also my last question what tranny is in the truck, it has 4 forward gears with the first one being a granny I think, in that it is not synconized with the rest of the tranny. So is it an SM240 or an SM465?
