Hey charles, i would like to make this mod, did you end up making a guide? I was told by two experienced subaru guys that 'legacy and ea82 knuckles are a direct replacement on ea71 cars and have much better brakes'. I very much compromised the brake assemblies that came on my car (welded the rotor to the caliper trying to get the castle nut off lol) because i thought i was gonna have no trouble replacing the knuckles. Your thread here is the only example i've found so far of putting newer knuckles on a 70s leone, so thank you! I've been reading the forums for a few hours and i'm starting to go cross-eyed, can you clarify if the mod for the end of the A-arm is for fitment or for widening the track? In other words what is the path of least resistance to getting EA82 brakes on an EA71?
