got a bad one in my 69 f100 and happen to have a spare one in the 350 cab.

q is its bigger, clearly the 350 with duallies and being heavier of course it needed more boost, so i will have to apply the pedal lighter lol

aside from the obvious i noted above, anyone know if there will or would be any real issues i may run into ?

thanks for helpful info that may come up

i have the orig 69 shop manuals (5 or 6 books) and the only diff in descript between the 100 and the 350 dash mounted boosters was the 350 lists it as disc instead of drum brakes - all other info was word for word

may as well give er a shot, gotta start stripping 350 cab anyhoo

shouldnt be a problem just use your master cyl if it will bolt on
if not just hook up your lines to the master
the diference is in the proportioning valve
some masters for disk brake have a built in residual presure valve
it could cause your drum brakes on front to drag
reason i saiy to use your master if posible

u know, it wasnt this tight when i was 21 with my 68 lol

going inside cab with out engine on my 71 cab is a treat - acrobatic maneuvers with the 69 engine in as a 'treat'

yeppers on using my m/cylinder, the way i pull em is no bleeding required (fingsers crossed ) cylinders are hanging ready to connect - no need to disco brake lines

lots of wd40 prior and lots of bitch rusted nuts but they are both side by side now, lol

clearly the air loss out of mine was round the plunger - effin dangling when i pulled it out

heres a few pics up to bench cleaning, now to mount er in

Does the same thing vacuum on the one side allows the 14.7 psi of atmospheric pressure to help you in apply the brakes
