Identify rear axle ratio

RS2600

Hi all,
Just bought myself a 95 SC with a warmed up engine, dyno says 330 rwhp. Don't have the specs yet but it's moving along quite well.
Looking at the door jamb data plate AX=9 and TR=LKKJJ. Been trying to decode but no luck. Any help appreciated. By the way car is
a Canadian car with km/h speedo.
Thanks,

If it is stock it is probably an open 3.31 for the auto cars. Thats what mine was.

And 3.31 isn't listed in the Tccoa article so probably a good chance thats it.

And the other 95 auto I have here has the code "9". But Id have to lift it to see if the stock tag is on the housing to see what that says.

There should be a tag on the diff housing that will have the ratio on it. Would be something like 3 31 for an open 3.31 or 2L73 for a locker 2.73.

I suspected that was possible, I remember A-Train posting about those cars years ago. Never was under one in person to see it though.
 
If all else fails jack the car up and spin the rear tire 1 revolution and count how many times the drive shaft turns............:p
