The best and easiest way to get the pedals closer is to do what is described above by Merlin:
“The other common method was to remove the existing pedal cluster from the donor car, cut a new hole in the side of the tunnel and re-install the pedal cluster in the original manner to the side of the tunnel by shortening the cables inside the tunnel to match the new location.”
The accelerator cable is easy to shorten, the clutch cable needs to be shortened and the brake pedal rod to the master cylinder lengthened.
You may get by only having to drill one hole…put the front hole of the pedal assembly in the back hole that now exists and drill one new hole for the rear pedal assembly hole. I drilled an access hole on the opposite side of the tunnel and then made a small patch.
