I use the stock 60s time period Ford F100 bake parts which are still available and can be found for very good prices. Problem is you need the backing plates! I use the F1 backing plates, but there are two issues, one the plates are getting a little harder to find (and costing more) AND you also have to have the F1 hubs. Early F100 parts will also work but about the same issues. I have articles (but have never attempted it myself) on modifying certain years of backing plates to work with different years of common brake parts. Bottom line is (as far as I know) all of the brake parts are easy to come by and fairly cheap, it is the backing plate that are harder to get.
