Just to share a little....
I used a 1 inch unit for the back brakes and a 7/8 for the front with a Tilton short 7/8 master for the clutch. The short unit allowed me to move the pedals back quite a bit. I also used banjo fittings to further reduce the space needed for the pedals. I added a toe clip to the accelarator and changed the cable location for a straighter pull.

I wish mine were stainless! That looks great.
