Looking for the OEM power booster that was an option when the truck was new. I believe its part# C5TZ-2005-C & likely NLA.
Or any other solution that won't require major modification.
Looks like this:
I purchased mine from a local auto parts place O'Reilys the booster does not
come with the two metal brackets that you have to have to mount it to the
firewall. I don't remember the part number but you can look it up on line
it was a Cardone rebuilt vacuum power assist booster. I wish I would have put
it on many years ago. Works great. You also will have to extend your wires that
go on your stop light switch. The project is easy to do. Good Luck
No Ford dealer or obsolete parts vendor has either part number.
Well that's just too cool I thought it was only available on the f250 in 66. I have one I pulled from an f250 and am planning to install it when I have time to resume work on my toy. My house has taken priority in preparation for the holidays.
If the four hole dimensions on the firewall (where the booster brackets bolt up) are 2-1/8" vertically by 3-5/8" horizontally, a '68-'77 F100, F250 or F350 booster would bolt up to the Slick.
The only other factor would be the length of the input rod running from the attachment point on the brake pedal to the back of the booster. On a '68-'77 truck, this length (for a non-bellcrank [cantilever] bracket assembly), from the back face of the bracket, where it interfaces to the firewall, to the center of the input rod eyelet is 5-5/8" in length.
The '68-'77 hole pattern (where the booster studs would attach to the firewall brackets) is 3-5/8" vertically by 3-13/16" horizontally.
I installed a dual diaphragm booster/firewall mounting brackets in my '69 F100 that I pulled from a '75 F350. --I originally had manual 4-wheel drums but converted to front discs from a '77 model F100.
It's probably best, if you have drum brakes at all four corners, to run a single diaphragm booster and not the more powerful dual diaphragm version. Otherwise, you may have very sensitive brakes. Drum brakes are self-energizing. Discs aren't.
The '68-up single diaphram boosters are not very different from the boosters that were available in the Slicks. If the dimensions I listed are the same for a Slick and a booster for a Slick cannot be located, the later model boosters would be an option to have a power brake booster in the earlier model truck.
This is a single diaphragm (non-bellcrank bracket assembly) booster from a '68 F250. You can see the bracket and booster design is very similar to the OEM booster/brackets that was previously posted for a Slick.
