I have a 1977 I'm trying to put back on the road after years of neglect. I have it running and driving but it needs brakes. I've read a little bit about using the calipers and vented rotors from a 1983+ car. Since I'm going to be replacing rotors and calipers anyway and those have better availability, this seems like what I want to do. Can anyone confirm what I need for this conversion? I've read just calipers/rotors on a 'stage 2' first gen but the info seems unclear on 'stage 1'. I think my 1977 with dual headlights is a stage 1, right? I read something about swapping on EA81 knuckles to make the calipers work. Has anyone here done that?

Hey did you ever find out the answer to your questions?  I have a 1977 Subaru standard wagon. Everything is running and good to go except whoever had it before me stripped the calipers off it. They are not easy to find. 

I think you have a stage two , not that it matters. Stage one is the same at the wheels. 

 

Whats the mfg tag say on your car ? Look on the drivers door. Just curious. 

Early Coupes had disk brakes from 72 onward. Standard line didn’t get disks until 1976 I think. So only 76 and 77 stage one which are nothing different than stage two 77-79.
