do you have side start fullcrank around ? i know top of the crank is different it had a flat side to locate the flywheel but wasnt aware the bottom of it was too !
now you know how easy it is to remove it find another and measure the O.D of it , see if its the same then knock it off and try it
i think i only have the one here and it is from a 550 so not much help really , should need to machine one up im almost sure ! try another side pull 1st that doesn't have the pulley already on it
