Hi, I was wondering anyone knows of any other gear ratios for the 5 ton axle? Had a line on 3 axles out of the fire truck with the air lockers and 5.81 gears but the guy sold'em out from under me when someone came in with more money. Guess peoples good word don't mean s***. Anyway, I know some of the old Autocars way back had some of the Rockwells, I remember reading about an SSDD or SRDD some type that was compatible. Also know that the old Autocars had a bunch of different gear ratios so was wondering if anybody had any information about the gear ratios or what else they were in or anybody has a line on three axles from M1500 crash truck.... really want to stay with the top loader axles which is why I'm looking for the gears. Thanks for any info.
