2006 Mega Cab Diesel - How do I tell what the stock differential gears are? The window sticker didn't specify anything other than that it is limited slip. Anyone know of a VIN decoder or any other way to tell? Thanks.

with auto and no ratio option you should have a 3.73

 

what about a stock auto '99 Quad 4x4?

 

don't know that one

 

the 99's probably got 3.54's
