Even " not being on the list" the SI/II brake drums are completely different from all later Alpine/Tiger ones since they carry external weights with balance bores. Weird designs and not easy to reproduce at all. Regarding the early front rotors they are also different than the later series. Slightly smaller diameter and least 2 different original thicknesses. Remember shims were used to center brake calipers on the SII. Not easy stuff too. Speedy Spares in UK used to repro early series rotors where I bought a couple of sets earlier. Don't think they are doing them anymore since they'll go out of biz soon. A pity though. Have a couple of comparative pics somewhere. Just need to find them
