disk brake confusion conversion?
I have a 68 f100 and i was wondering what all i need to get from pull apart. i work at oreillys and going to buy most things new (rotor hub assem., caplipers, hoses, and booster/master) from a 1973 f100. what will i have to get from the 73 at pull apart? ive read different things on these forums. also i read in one that the f250s and 350s in my year came with disks. if i got those instead would those be a better match up?

I'm in the process of swapping discs from a 78 F100 to my 70 F100...basically scraping, cleaning, and painting at this point for a mega-parts and rebuild thrash next spring. From the donor I grabbed the radius arms, I-beams, spindles, rotors, calipers, rotor shields, and the proportioning valve. I lucked out on the steering because the PO did a PS swap and used the pitman arm with more angle. Ford did an engineer change so the pitman arm you need is one with a D2TA casting, the version with more angle. You'll also need the corresponding tie rods (right, inner left, and outer left). I simply cut the brake hoses because they are cheap.
If using 73-75 spindles, you'll need to use the king pins for 73-75. If they're 76-79, then king pins for the 76-79. That is, only if they are being replaced.. but make sure you document the year truck the spindles are pulled from.
As far as the booster and MC, yes I do recall MCs (PB or MB) were compatible to 76. Same with the corresponding booster.

F250s and F350s were starting to be equipped with discs but they've always had eight lugs. 'Puts the kibbash on that idea.

I guess it keeps us posters busy trying to help those finding their stuff doesn't work.

So you think this mix and match hoping 
you can remember everything is better than getting everything from one source and not having to worry about it, is a better way to go & to recommend to others?

There is nothing wrong with mixing and matching so long as your research indicates they are in fact compatible. Plus, if you or the subsequent owner ever needs replacement parts, the record will show where/what year the part came from.
In my case, I would have unnecessarily bought a pitman arm I didn't need if I blindly bought the entire front suspension and steering components.

ok heres another question. if the hub assembly is useing the same bearings as the drums that are on the would the not just fit right on? and if not the same exact bearing as long as the ID is correct the should fit, no? also i have not gotten an answer about the disks from a 68 f350/f250 besides that they are 8 lug. (no big deal i need new wheel anyways). so would those not go straight on? and as far as the 73-75 i did gfind one at a pull-a-part but do i HAVE to pull the king pens as well? they looked the same as on my 68. this whole thing is so confusing. i wish i had the money to buy the kit or a whole parts car but i dont. thats why im just trying to get the stuff i cant get from work.

Here's why: Though the bearings may be the same, what is the dimensional difference btwn in the inner bearing and the outer bearing when they are mounted in the rotor? Though they have the same ID, it might be that they are physically farther apart.
My experential knowledge is generally limited to the half-tons since that's what I have. However, my assumption is that the F250/350 series are much heavier duty and likely have larger components like the rotors AND the spindles since they have higher load capacity. By simply crossing part numbers indicates 66-74 2WD F100s share the same king pins as:
71 2WD F250s with 3000 lb front axles;
72 2WD F250s with 6900 lb GVW; and,
73-74 2WD F250s with 6900 lb GVW.
I have no info on 68 F250/F350.

1968/72 F250 2WD's & F350's were available with optional dual piston caliper disc brakes.
Since these trucks have 8 lug wheels on a 6.50" bolt circle, not one disc brake part will fit any F100.
The only part that is the same are the F100/250's lug nuts.
The wheel bearings are not the same. If anyone claims they are, they are mis-informed.
1968/72 F250 2WD & F350 w/disc brakes: C8TZ-1216-A outer bearing / 8A-1202-A outer bearing cup / B7A-4221-A inner bearing / B7A-4222-A inner bearing cup.
1968/72 F100 2WD: C3SZ-1216-A outer bearing / C3SZ-1217-A outer bearing cup / B7C-1201-A inner bearing / B7C-1202-A inner bearing cup.

ok now after asking that. is there anyplace to buy new spindles instead of getting use from a pullapart. I priced everything through my work that would come in the rebuild kit (rotor assembly, calipers, hoses, booster/master, ect) for only 300$. gotta love paying inventory price. but one thing we do not sell is the spindles and that is mainly all i need for this project.
