I bought an ae85 LSD diff head off a toyspeed member some time ago and finally got it into my car, but its definitely not LSD. only one wheel spins.
could it be he was b*llshitting me? and seeing as I wouldn't be able to tell a standard diff to a LSD diff myself i didnt notice its not...
or could the LSD gears or something just be buggered and not working properly? or would the whole diff be stuffed then and not even driveable?
