Yes you have to use the 78-79 RA so you can't use the 80-96 ones. there are some custom ones that you can use. If you remember I said that I did mine with the most stock parts as possible. So you can use the stock 78/79 RA mounts but there are others out there.
I still need to get a "real" alignment. I've done my redneck one but I'm not sure if it is good enough.
not true brother..
there are tons of people on here with the sas and 86-96 ra mounts including myself. you do need a rabushing kit from a newer bronco to make it work
