Disc brake conversion

What's parts from a 76 2wd with disc will work in a 74 4x4 front disc conversion? Master cylinder, booster, proportioning valve, pedals? Obviously the spindles likely won't.

Pressure valve is plumbed a tad different but same valve. 2wd has a plug and fronts are spliced where as 4wd fronts are ran separate from factory. I doubt it made any difference?

The calipers are the same but the actual hard lines into them are different for they go upward into a bracket on the frame on 2wd and downward to a bracket on the axle on 4wd

The pads are the same as well along with the caliper mounting pieces.

Rotors are way different.

Great, at least I have the cores for a lot of the parts. I'm guessing the pedal assembly goes with the booster? Will in be a direct bolt in exchange for booster?

Upper pic: 1973/79 F100/250 2WD w/single piston calipers.

Lower pic: 1976/79 F100/150 4WD

2WD's don't have 2B292 caliper anchor plates (see lower pic), so the calipers do not mount the same way.

The 2K004/2K005 splash shields are specific to 2WD or 4WD
