Hi chaps, not meaing to stick my nose in here, but you might be worrying unecessarily as its the actual mould that can not be changed once done - everything else (hole positions etc) can be done differently each time - if you provide details/measurements to FL.
So as long as the shape of the chassis from TopCat to Works has remained constant - which i think it has - then you'll be golden.
This means that you can also change electronic/cell locations use stick or saddle packs etc etc, in fact you can do whatever you like within the bounderies of the mould
