Matey,
The installation looks ok to start with...a little low on the bulk/pedal....but to achieve the full installation of a bias set-up you will need to do a bit of welding...your pedal and hole alignments look ok but as Martin says you will need to weld in a strengthening plate to cover the original hole and prevent the bulhead flexing....i was asking about the tube as without this being welded to the pedal you wont acheive an offset pivot (the key to the bias setup)...and as Rich says without this offset pivot you will never acheive more front braking force than rear...once you have sorted these few problems out and got your pieces welded in the bias should work nicely without the need for a pressure reducing valve in the rear line....
The 2 master cylinders should be different sizes..in general front should have .625....rear should be .70
HTH
