Disc brake questions
I've searched and am confused so I have a couple questions.
The truck is a 1968 F350, i believe it has the 12 1/2" drums. If so I can use those spindles correct? If so I will only have to buy a hub/rotor assembly and the caliper mount bracket, correct? I have the proportioning valve. I want to use the dual piston calipers as it's an f350. Do they require a special caliper mount?
Are the drw front hubs available new or do I need to source them used as well. Can the hubs from say a 1989 drw truck be used?
Or, is it best to just go buy a parts truck?
Thanks in advance
Will

1967/72 F350: 12" x 3" drum brakes front/rear. 1973/79 F350's with standard equipment disc brakes. The rear shoes are 12" x 3."
1968/72 F350's were available with optional dual piston caliper disc brakes, and if so equipped, the rear shoes are 12" x 3."
12" x 2 1/2" brakes were introduced in 1966 F250's, but it depends on the GVW, because some F250's have 12 1/8" x 2" brakes.
1968/72 F250 2WD's were also available with optional dual piston caliper disc brakes. When so equipped, the rear shoes are 12" x 2 1/2."

So if I find a 68/72 it's a bolt on swap if not will I need spindles and brakenpartsbonly or will I need the entire I beam? Wanna make sure the kingpins didn't change size.
Can dual piston calipers be fitted to single piston holders?
Thanks again

1968/72 F350's with disc brakes are not easy to find, and since you also want P/S, buy a 1973/79 F350 donor. That way you'll have all the parts you need.
While P/S was available mid-year 1969 thru 1972, it was an option, so not all F350's had it. P/S became standard equipment in 1973.

No, they will not. Like number Dummy said, buy a 73-79 F350 donor, then the entire suspension, I-beams and all, will bolt into your truck. You can also take the power steering, master cylinder and brake booster as well. It's so much easier to use a donor since you can take the lines and everything. If having a donor at your place isn't feasible, then go to Pull-n-save or equivalent and take everything you need off one of theirs. The wrecking yards are full of these trucks. Good luck.
