Hi Pete
That shaft is well out of alignment! 
So far the things I've found wrong . . .
I had to cut and split the nuts on the P&D tower as they were glued. Lucky I had some spares from the OE tower.
The P&D gearbox was assembled the wrong way around - and I didn't find it until after I had fitted the lower sprocket. Lucky I hadn't glued the nuts.
The shaft on the Finescale tower is 3 mm too long to allow the tailshaft to fit between it and the motor. Lucky I had my handy Dremel to cut the end off.
The fourth P&D truck has no shaft for the bottom tail shaft, so I couldn't change them over. Lucky the existing one had a straight axle.
All in all, a lucky day. 
I won't be able to finish it as I have a band gig tonight, so I have to get ready.
Cheers
