... really? A 77 would have disc brakes as OE equipped.

HIO is correct, a 77 would have been disc either way: all 73-79 2WD had front disc and same for 76 and later 4x4. I am assuming you are looking for a 2WD based off the comment for sites only listing up to 72 for conversion kits. They would not list later years, because they already had it. If yours does not, then some parts have been swapped from an earlier year truck. So for clarity, are we talking about a 2WD or 4x4? Pictures could help identify what was swapped in.

My 78 has disk on the front and that in nice. I wish I had disc brakes on my 69 F100. I have the fenders off and easy to get to. Now to make the change.

on front.1973/79 F100 2WD: Manual disc brakes were standard equipment, power disc brakes were optional.
1976 was the first year F100/250 4WD's were available with front disc brakes.

I ust completed a 2nd gen Explorer/Mountaineer rear disc brake adaptation on my '79 Bronco. The truck has the early large bearing Ford 9" axle. It was extremely simple, very cheap and the braking performance is excellent. The parking brake feature is another big win.

Anyway, from what I understand I need to get the backing plate and calipers from the Explorer and then redrill the rotors and hub center. Is that about it?

I can't speak for the adaptation to another 8.8, but for the early big bearing Ford 9" axle, the Explorer backing plate holes simply needed to be slotted out with a die grinder to match the bolt pattern of the early Ford flange. I had to use a 0.2" spacer between the wheel bearing race and the inside of the flange to obtain the correct bearing preload as well. Redrilling rotors, or purchasing new from Currie pre-drilled solves the rotor problem. These brakes have an integral drum brake that is used for parking brake ONLY, so they do not wear out very quickly, if ever. Also, adjustment is very simple through a hole in the backing plate, if needed. The brake performance is stellar.
An interesting note is that using 2 passenger side e-brake cables from the Explorer adapted almost perfectly to my '79 Bronco. I only had to extend the inner cable ends by about 6" and I have excellent parking brake now too. Very cheap if you can find a good donor axle from the junkyard.
