I’m trying to figure out the differences in the big bear sub model classification or differences between them all to order correct parts. I own a 1997 big bear yfm350fwsj as per the owners manual I have. I can’t locate any parts for the FWSJ model. Does anyone know the difference in the one I have and the normal FW model? I’m trying to order cv axles and the ones I ordered did not fit correctly.
