Hi
I kind of re-designed the book's pedal box, mostly to use 25x25 square section tube rather than flat plates for the pedal shafts.
I have it in my Roadster, and I know a couple of other builders used it too, with some improvements. If you are interested in it, I made a construction guide that you can freely download here:

There are threads on my blog about it too, here:

It is not the the MT75 chassis dimensions, but you just have to shorten the lengths of the plates and recalculate the pedal spacings. It is not exactly what you need, but it could be a start, or give you inspiration to adapt it to your needs.
Hos this can help
