the F100 brakes will fit. You need the hubs, backing plates and other hardware, including drums naturally.. There has to be a minor mod to your spindles and a mod to the inner bearings to make everything fit. The stock master cylinder should work ok with the F100's, but you will need some 1/4 to 3/16 brake line adapters which should be available at any parts store..
There have been numerous articles about this. I have copies of one such article done by a well known hot rodder. I will send you a copy if you give me your email address. It gives all specs, including bearing, seal numbers. email or pm me for the article, but I will need your email address to send you the article.
As these are self energizing brakes, they should be better than the stock brakes even though the stock brakes are bigger.
This is for fronts only. For rears, you will have to go to the aftermarket.
