if the replacement 1.5 pinion is brass it will go on the scaly splined shaft easely. providing youve got a pinion puller pusher tool. if not buy a cheap ninco one, not the best!but its given me years of use. if its a steel pinion, remove the splines with a fine needle file while the motor is spinning. you can do this to the standard scaly FC 130 motors as well loads of peole sell reducer sleeves to fit a 2mm pinion on a 1.5 motor shaft. john and bin the plastic pinions, use brass, steel, stainless, or the anodised alloy ones.

i think all the cars that use the motor shaft to keep the pinions in mesh are 5.5mm dia. john
