Ok i might be able to help you a bit. I have a AE71, the AE86 panhard rod bolted straight in, i've got AE86 coilovers for the front, for them to be installed you need 86/aftermarket strut tops, 86 steering arms and brake setup. But thats as much as i can tell you, because thats all the AE86 i have in my car at the moment. Oh and i have some AE86 superpro contolr arm bushes here, which i am pretty sure will fit the AE71, but i will find out for sure sooner or later!
