brake questions
my 1973 f100 2wd, has manual brakes ( disk front drum back), my question is if i buy a new brake booster and master cylinder combo, can i just bolt it on and go, i have the mounting hardware, so what else would i need for power brakes?

Booster, booster bracket, check valve, hose, and an available vacuum source.... maybe longer hard lines cuz the mc moves forward by a corresponding amount.

I have the mount off a donor truck have the check valve and hose for the vacuum and a fitting for the vacuum, I think the lines to my mc could be moved forward with ease so that's it?

I don't know if they're compatible or not, but NumberDummy has said in the past that there are 22 different brake pedals for these trucks:

Power brakes use a different brake pedal than manual brakes.
D3TZ-2455-A .. Brake Pedal-Use with power brakes / Marked: D3TA-2455-AA
D3TZ-2455-B .. Brake Pedal-Use with manual brakes / Marked: D3TA-2455-CA
Make sure the pedal you get is marked D3TA-2455-AA because...
1973/79 F100/350:
There are TWENTY TWO different brake pedals, NINETEEN different master cylinders, SEVENTEEN different power brake boosters and SEVEN different clutch pedals, I kid you not!

I don't know the one on my 73( manual) was exactly the same as the one of my part truck 77( power) so I don't know if it had been modified or what the deal was, where is the number on the petal?

so my truck is a 73f100 manual/brake, and the part truck was a 77 f-150 power/brake( no longer have the pedal) but the measurement were exactly the same height from floor, distance from fire wall, hole size for the bolt to go on, the, I guess what im asking is, will my 73 f100 manual brake pedal work if I put a booster and correct hardware on it? or will I have a problem?

ok heres the number off my 1973 f100(100% manual) petal D3TA-CA the other number is 10-8-72, based off this what exactly would I need to do to put power on my truck?
would I need a pedal off a power truck or can I make mine work?

That I don't know - mine has manual brakes and I haven't converted to power or tried to compare pedals; I just know that NumberDummy always says there are bunch of different pedals - something must be different between them, but I don't know how much is just lever ratios and how much is positioning of the mounts/connection points.

my grandpa says they have done it before just put the mount and booster and had no problems with pedal or any thing else, but I had a 77 part truck and the pedal looked exactly the same as my 73 manual so I dunno what the true difference is , but do see what he means by 22 different pedals( although my buddys 74 has the same stamp as mine( 73 manual) and his is a 74 f100 ( 4 speed 351 with power brakes)
