Does anyone know if the Way profile on the M250 and M300 are the same? They look it but I'm guessing form pictures. I'm after a bed stop, rather than make one i know of one going cheap but it's for an M300. Also, i want to build my collection of change gears, again they look the same in photos? I know some parts carry over, and some accessories such as the Taper turning Attachment are the same. Any pointers would be much apreciated.
