The website HH56 pointed to above shows a 5/8 master cylinder. It also shows a push type slave cylinder. Does not indicate diameter of slave tho.

So why wouldn't the following set up work:

1. Use the 5/8 master cylinder mounted at the toe board.
2. Obtain a 1" or maybe 1-1/4 inch push type slave cylinder.
3.Obtain a readily available modern power unit and 1" master cylinder assembly - for example a 1996 Explorer master cylinder and power unit.

Mount the 1" slave to the Explorer power unit on the PEDAL side of the unit. Mount the Explorer master cylinder to it's usual place on the front of the explorer power unit.
This makes a 3hree unit assembly that can be remotely mounted.

Run a brake line from the aftermarket 5/8 master cylinder at the toe board to the 1" slave of the power unit assembly.

The 5/8 master cylinder to 1" Slave clinder will give the HYDRAULIC EQUIVELENT of about a 2.5:1 pedal ratio. Maybe a 1-1/4 inch slave would be better.

Of course there is always the stroke of the slave and master cylinder combination to consider too.
