Power brake conversion question-what gives??
I am planning to convert from standard to power brakes on wife's '66 F100.
Old standard master cylinder had a rubber boot on m/c and when bolted up to dash, m/c unit sealed up hole from engine compartment quite nicely.
New booster unit has a boot also, but it is too short to properly seal the hole in the dash left by old m/c unit.
A search of the parts manual shows up nothing in the way of what part may be missing...
What have others done here??

power brake booster push rod seal
I am in the exact same boat as you. My rubber boot is to short. All I can find is a seal for a 65 ford fairlane (part# C0AA-2A021-A). Looks like what we need but I don't know if it will fit. They run $10. Does anyone else know where to get this?

How long does the guard have to be? There's another that's 3.82" long (C7TZ2A021A), but no one has any.

The missing part is a plastic sleeve...as Bill noted above...its notched to go inside of the firewall. Its around 1 1/2-2" diameter..its a hard find on the early trucks....I dunno what the later trucks used for this pourpose.
