You could try the zanussi TC450, the earlier version of the 470 which came fitted with an electric fan motor fitted on production, not sure about the price, probably not much different to the complete kit.
The kit gives you the fan motor, capacitor, wiring, new backplate, seals for backplate, additional wiring & wiring instructions. It’s intended to modify from the old belt driven fan to the electric one. Motor will be the same as the one in the t/d already.
