Moving the pedal box backwards?

[jps]

Any advice on whether this will present any problems? As my chassis is to fit an MT75 box the footwells get rather narrow. I've got a narrow pedal box in component form - but from looking at the main plate the pedal spacing seems far too close for my feet to actually operate them!!!

Is there any pitfall to using the wider (book design) pedal box and just positioning it further back in the footwell. I guess i'd need a plate going to the front panel that supports the steering column - is there anything else to consider?
