Chev/GMC diff ??

[340SHORTY]

what were the factory options for posi type units in a 78/79 3/4 ton 4x4 truck? I know its a 14 bolt but it appears to be a detroit locker. Is this possible? thanks:corn:

Anyone could have dropped a detroit into the 4 spider case but if it is a 3 spider set up it's a gov lock.
