DalaGStanator's Customs, Mods and Experiments

Assuming it was a pre-2014 FP Talking Percy (dark red battery+speaker truck with coal cover), he originally has a different drive unit that's shaped more like the Thomas type (also in the Thomas and James from that range). I don't know whether a Flat drive could fit in that chassis without mods, so how did you do it with him? You probably gave him a Thomas DU like a regular Percy would have. The Flat type also needs a different gear on the driving axle, meaning the one from a Thomas drive engine may not fit.
