yep,, all it needed was 2 more shims on each rear wheel... (good thing i had a 3 wheel skid laying around for parts)
the wheels actually measured 12" from inside to inside,, which is the same distance as the outside of the drive lugs,, the 2 extra shims on each side brought it to 12 1/4"... a couple adjustments to the alignment and it looks good to go...
picked this track up for $60... 192 studs (- pullouts),, all the clips are there & in decent shape,,, and looks to be pretty low mileage (all the nubs on the lugs are still there)... whatta deal,,, kinda feel like i ripped the guy off but that was his asking price...
