as long as the pitch is 2.52 and 1" lug height or. under some people may confuse the 3" pitch 120's for 121's.
i assume your referring to the inner drive lugs on the track? all will have 4 rows. some sleds will have 4 drive wheels, some 2.
depending on where the missing lugs are torn off at would be an indicator. partial lug still there, good to go for awhile. torn down to the cords, think twice.
