There are some aftermarket 9" rear brake kits available. A few are designed to work on multiple housing ends. I used to sell a kit from Afco to my clients who wanted an 8" kit, that could also be used on a 9" if they upgraded later.
( I assume it's a 9", but perhaps it's not? )
I cannot speak to what OEM front brake kits are available, without doing more research.
Researching the big box speed shops like Summit Racing will give you some quick ideas.
If you want a more specific kit, then identifying which housing end pattern you have currently, as well as the axle offset. [Distance from housing end to outside of axle flange. That can usually run between a distance of 2.25" to 2.5".
There is 1 offset that's in-between as I recall. If your not completely sure whether you have a 9" Ford rear-end or not, you can take a deep well 9/16" socket (needs to be long like a deepwell).
You put it up onto the very bottom nut that holds the center section in place. So out if the 10 studs holding the 3rd member in, your looking to put the deep well socket on the nut at about 6 o'clock. If the socket WILL NOT go on straight, it's a 9". If the socket does go on straight, it's an 8". If there are no nuts & studs holding in a 3rd member (doubful) than you have neither an 8" or 9". That might be a Salsbury if memory serves me.
Good luck, & sorry I couldn't be of much help.
BTW, as you likely know, Disc brakes on front are much more a worth while install than in the back. I only mention all this incase your planning to swap out both ends to disc.
I can't speak to the Front hardware available using an OEM brake setup from another Ford vehicle of similar era, but I can tell you it's getting VERY hard to find the Ford OEM rear brakes, from discs offered on stock vehicles. They will likely require swapping other components as well,, like the axles, due to the standoff distances being different.
If your very handy at machining & reworking bracketry, than most anything is possible of coarse. When you consider your time to have value, then it can be better to buy what fits straight out of a box.
