420G/MKX conversion from auto to Tremec Magnum 6 speed

I am going to convert my 420G RHD from auto transmission to Tremec Magnum TR6060 6 speed manual. Where can I buy a pedal box for it thanks.

only two ways I can think of,

  1. obtain an original manual MKX/420G RHD pedal box from a wreck (but that would be rare and lucky)

2nd way (dont know if its possible, but is what was done with my XJ12 auto to manual conversion, which is modify and fabricate 3 pedals to fit the original auto pedal box, instead of the original 2)

Thanks Tony. I think the chances of locating a 420G manual pedal box are just next to zero, so I will look at your second suggestion. The Tremec Magnum 6 speed has a tri - location gearstick arrangement but I may have to have a gearstick like a 427 AC Cobra leaning forward and the front seat may need modification too.
