Repairing the Tomica 'Charge Play' park-o-mat,

I'm definitely getting closer here, right thickness but not sure if it's the right size? It's a pullback though. I'm thinking if I swapped the axle from one of these [note the casing would allow for an axle to slide right through] to the one from the original motor, then i'd be in business. Still going to wait on VIGOR responding to my email query, but if they don't i'll just get one of these in the closest possible size and hope for the best.
