lol i must ahve really explained myself wrong! im not after jap option ect
what im after is how to tell the individual parts!
for example:
i might be checking out a hachi that is aus spec but has had a 4age with t50"jap spec" gearbox, how do i tewll that its a "jap spec" gearbox and not an aus t50?
and similarly if i look under the car how cn i tell if it has a t series diff/axle?
