2 sets straight from the military m1008 k30's. located in fort smith, arkansas. both sets are 4:56s with the detroit in the rear. i know for sure that one set came out of a running driving rig, but i cant say on the second set. all four axles turn freely and easily. lockouts turn free and easy. the casting numbers on the diffs are both 030486, so im guessing they are of 1986 vintage???? the odometer on the running rig the first set of axles cam out of was at 28,897 miles. asking $1600 per set. open to some trades too. reply or pm.
