I called a Differntial Company this am to inquire about their Diff...

I ask price and application, Im told it will fit the R200 rear end of a Nissan 240sx. Im told this is from 89-92 (s13 Obviously) I've never heard this before ? Its usually by chassis code. Is this the correct info ?

Im skeptical due to the fact when I asked if the Differental was Mechanical he said "whats that? No its a clutch type" Im thinking to my self Uh.. I used to OWN one of your diffs I know you make a 2 way Mechanical diff.

I talked to him and tried to explaine to him what a 2 way was, during the stint of our conversation he stated that "our differentals dont lock" Im "like they dont" ? Ummm.. how do you get both wheels to spin ?

sigh.. So now Im not too sure about this place
