Seems to me that in a car that will be shared between two people of different leg length that rather than having a movable seat (and the shorter driver ending up too close to the steering wheel) that it would be better to be able to move the pedal box.

I know the early Marcos cars had this arrangement, because the seat was part of the rear bulkhead, and the pedals could be moved by turning a wheel, so I assume the pedal box was mounted on a threaded rod of some sort.

The lines I am thinking along are pendant pedals, master cylinders connected to reservoir and brake pipes by flexible pipes, the whole being mounted on a plate that is able to move along a couple of plain rods, and the position controlled by a threaded rod (just like in a carpenters vice, if you know what I mean)

Anybody know if anyone has done this recently, or whether there is even a commercially made product that would be suitable?

i know it will sound stupid but shorter people have shorter hands as well.

Sounds possible, if a bit fiddly.
Have you considered your accelarator pedal? If it cable then it might be ok.

p.s. Give the shorter driver thicker platform soles

I know that the CC Cyclone kit used this arrangement. Also, many aircraft use movable rudder pedals and fixed seats.

As I recall, the Cyclone had a couple of fescalised (shiny!) rods to guide it back and forth and a threaded rod with a handle on the end. I'm sure I have a picture somewhere!

moving the peadals ony may create problems as the relationship between the driver and the distance from the wheel wont have been catered for unless you have an adjustable steering column like the VAG range which allow the wheel to be brought toward the driver

I should have said that this arrangement is being considered for a situation where the distance to the steering wheel will not need to be moved but closer pedal would suit the shorter driver better than moving the seat forward. Some people just have longer legs!

If you had threaded links you could move the pedal a little by adjusting these.

Also I think some racing cars had the pedal pad fitted to the pedal upright with a threaded stud and locknuts so that there was some adjustment.

Why not move the seat?

I have a fixed bench seat in mine which is too long for my legs, so I have separate lumber pads which are velcro'd to the seat back, remove these and you need 3-4" longer legs!

I believe one of the top of the range Ford Focus had an electronic movable pedal box.
The Sierra has a movable steering column that is a straight swap for a standard one

We could experiement with a bolt in pedal box with different bolt holes like Dax have, or the adjustable pedal pads as kindly mentioned above, but it would take a fair while to do a driver changeover, so if a cockpit adjustable solution could be found, then we would go to extra effort to do it.

The birkin seven has this very system. Its really good and easy to do.
Buy some slides from marchant dice and a lead screw with 2 bearings to make the adjuster.
The electric seat adjusters may provide that equipment
