FAST wont necessarily tell you that info

to my knowledge, CA equipped S13s were open diff… especially a J or a Q.

your best bet is to check it yourself:

jack up the rear of the car

spin one tire. if the other spins in the opposite direction it’s open. if it spins in the same direction it’s a vlsd.
