    It's got 5 lugs, 15" rims, drum brakes. it's in the back of a 73 shortbed I just picked up, but it isn't the original rear end.

    Thanks,

    WTF? A 5 lug 14SF huh?

    Dude, i think its a 2wd 12 bolt. :crazy: Looks exactly like my old 12 bolt but 5 lug is 2wd, 6 lug is 4wd.

    It's a 12b. The 12b's that came in 2wd trucks were 5 lug. 4wd trucks got the 6 lugs.:)
