boost on old 66
I found the entire set up off a 67 3/4. everything bolted right in. Had to adjust the rod. Got a new fitting from Napa and a rebuilt Master cylinder. Been a lot of years ago so I don't remember the part numbers. I might have the box (part number) with the old master cyl. inside but I am sure Napa can get one for you. I too would like to know about the booster in case I need one some time.

My plate is different than the one on our '64 F100. My bottom bolts are ~5 1/8" apart. The '64 appeared to be a little over 4" (it's dark out).
The '64 plate is square and my '66 is 5 sided as if to cover a hole above it.
Does someone have the measurements of the holes in some of the different booster brackets?

The odd plate you have is the firewall reinforcement it differs on how it mounts and looks relative to the 61 to 64 plate. You can redrill the plate to accept a later bolt pattern booster brakcets. Use the same counter sunk screws as the master to attach it.
