rotor question

so I found a 80 f100 up for parts and I can get the rear end with 5x4.5 bolt pattern out of it my question is I also found a 76 f150 that I can get the spindles off of can I run the front rotors off of a 80 f100 with the 5x4.5 bolt pattern on the 76 spindles with 76 calipers if I put them on my 68 f100

I'd go to rockauto.com and look up the P/N's for each for a fast answer.

I know bearing companies have books which lists bearings by size so figuring out which bearings and their races could be found. But I don't know if the rotors would line up with the calipers though.

jeff the bearings are the same for both and I know that they both take a floating caliper the only thing that I am seeing is that the rotor for the newer truck is about half an inch smaller in diameter this would all be a temporary thing as I want to do the cv swap eventually but the parts that I have found don't just pop up all the time so I guess my main question is will the smaller rotor be a bad idea or unsafe

If the brake shoe extends beyond the radius of the disc, then you will polish the disc edges, and step the pads in that area. If I had every intent to change the discs and pads in the very near future I would do it just to get on the road again. I certainly would not put thousands of miles on it.

2X Aesop. Brakes are your life. A good machine shop should be able to alter the correct rotors to the smaller bolt pattern. It is just the 9" rear axles can't be changed because of the 6th access hole in the axle flanges. With it there you can't add a 2nd (smaller) bolt pattern. The front rotors don't have that problem.
