I've always wanted to ask this question to someone which really knows. When looking at restored GT-350's and mustangs from 1966. Sometimes you see the coil mounted on the passenger side and sometimes on the drivers side. what gives? I'm guessing maybe the carry over cars (because 65 mustangs) might be different than those manufactured in 1966? maybe mustangs had coils placed different than GT-350's? Could be ford changed placement during the 1966 build year? Please school me! Thanks, Fred
