Found a Ford towing brochure that lists L9 as electronic locking differential with a 3.55 ratio.

According to the ( 1996 ) Ford Bronco Owner Guide : Axle code ( 19 ) is a Ford conventional ( non Ford Traction Lok / limited slip ) axle with a 3.55 ratio
According to the 1996 Ford Ranger owners manual : Axle code 82 is a ( 3.08 conventional ) ( not a traction-lok )
On a 1997 Ford Crown Victoria : Axle code X5 is a ( 3.27 ratio , limited slip )
L9
CG is 3.31
I believe the axle code is listed on a sticker on the end of the drivers door The axle code will correspond to an axle ratio Once a person knows the axle code , the ratio can be looked up
I believe axle code 19 is for a Ford conventional axle ( non limited slip ) with a 3.55 ratio

I am not positive about this but, I believe that this indicates that the axle has a 3.00:1 gear ratio. Check with you local Ford dealer for a definitive answer.
