tell that donkey he doesnt have a clue.

or.

tell him its "toyota 7.5 inch, same as hilux front "

he is probably thinking you have an E series, (also mostly found in tarago's) which is 7.1 or 7 can't remember, anyway, hes right about that, their arent any good lsds for those.

pretty much you can get every available desireable LSD for an F code toyota diff.

every JDM aftermarket brand. truetrac, detroit locker, ARB air locker ect.
