I need some info on the track drives for a little whip .I believe its a 1977 model with pararail suspension .I have some nos track drives put away for my tk sleds but not sure what the lil whip takes the part number is different in the parts book can anyone tell me what the difference is ? Even better does anyone know what can be used on this machine thanks in advance

well since nobody posted I will post that they are 252 same as older scorpion sleds replaced mine with the newer black ones not as prone to breaking .I have decide to leave the bogie suspension in there for now .It was complete and seems to work well . need snow to test it out
