1988 chevy k1500 shorty rc

hey sorry i never get on here anymore. i check fullsizechevy more often usually never this

i bought the truck with that axle.
i later found out why the axle was swapped, i can tell by the unatural lines in the driver side bed that the track must have been t-boned and must have broke the leaf springs and such, that and part of the frame had been bent and bent back.
i am pretty sure that it is the stock drive shaft as i just recently put new u-joints at both ends but i u-joints are pretty universal so that probably doesnt say anything about it being stock, sorry i can be of more help.
