Jim,
Having made my own, I would recommend buying one. It's something of a
pain to get the holes drilled in just the right place, unless you have a
large tool assortment it's almost impossible to drill the big hole
(1-1/2"?) for the base of the new master cylinder.
A word of caution, when you talk to the catalog people they may tell you
that you can't use the adaptor with a manual transmission, if you have a
4 speed it should fit with no problem. The kid I talked to at Master
Power said it interferes with the linkage! When I asked "what linkage?"
he didn't have a clue :-) They must think all trucks have three speed
column shifts.
One other thing, I would massively recommend against using a Mustang
master cylinder on a 3/4 ton. It will screw up your hydraulic ratios, no
matter what the catalog people say. You should use a non-power master
cylinder from a late 60's chevy truck with about the same bore size. I
used one from a 68 1 ton on my panel before I switched to front disk
brakes.
