Did a limited slip diff come with these cars, or was it an option?

Also how can i tell if its got one??? I know about lifting the car and turning one of the wheels, if the other turns you have one.

What about wheel spining it? Does that work.

Thanks.

Was an option, rare small case item. Jack car up on diff with both wheels off the ground, have car out of gear with handbrake off, turn one wheel by hand - if the other wheel spins in same direction it is an LSD, but more likely than not it will turn in the opposite direction, meaning its an open diff.

Best way to check for sure.

You can also check on the diff itself, if it has a S after the 4.10 then it's a lsd.

The best way is to jack one side of the rear up
out of gear and try to rotate the wheel.

^ No thats not the best way as the car will roll off the jack if you have a LSD
