Dapol class 67 chassis help

[Burkitt]

I'm considering using the Dapol class 67 chassis to power a 3D printed loco I'm working on, and I've got a couple of questions I'm hoping someone who has one can help me with.

First, I'd be very grateful if someone could let me know the wheelbase of each bogie, and the distance between the bogie centres/pivots on the model, in mm.

Second, I'm wondering about the underframe detail on the chassis. How much of the mechanism is in the underframe rather than in the body? Also, is the underframe detail part of the cast chassis, or is it removable?

 

Many thanks in advance,
