Try a manual... Chiltons, Haynes, etc. all available at your local auto
parts store or library.

The brake booster on my 81 F150 is mounted in the firewall in the
engine compartment. It is black 'pancake' type thing. Around 12" in
diameter, and 6" thick. The Mater Cylinder is bolted into it. I
suspect the 78 is the same.
When I replaced mine, there was brake fluid in it, so I also needed to
replace the master cylinder.

The piece you have should have a part number on it. R U asking about
just the vacuum assist piece or the combo of vacuum assist/master
cylinder? The combo unit can be purchased and is the best 'way to go'
in most cases. I am 'on' my 3rd combo unit with my '81 F100. What has
happened to each of the preceeding units was, the vacuum units' seals
began leaking which in turn caused the seal in the mc to 'go bad'(brake
fluid leaking down the firewall). The replacement combo unit costs
about $80(rebuilt). I'd just bring what you've got now into your local
parts store and match it. I believe there are only a few available for
the match.
