I would think, it would have to be off a 100,130, 200 or 230. The C grill is shorter than a super C grill due to the taller radiator and that is the same as the 200 and 230. The hand crank hole might be the other problem from a C grill, The pan is shorter.
They have the "grill bottom panel" on this site. Not sure if its what your looking for. $196.00
