Pedal box for a GTD

Since I bought my car I’ve been playing around with the pedal box trying to get it to fit me. I’ve cut, welded and bent, but it’s still not comfortable. Rather than mess around with it any more, can anybody recommend a pedal box that will fit? I’d even prefer an original GTD pedal box to the one I have.......
Just have to say a big thank you to Frank for the pedal box. A trip down to Hailsham was rewarded with a chance to see not only 3 GT40’s but a fabulous sprint car. Thanks again Frank
