If the rear end is original to the car and the tag on the driver door is readable, the axle code is listed on there. M is 2:73, Z is 3:08, and E is 3:27. Any of your guys' cars have the optional 3:08? I found my brother a '92 Feature car last summer and his car has them. That was the first one I had ever come across.
Door tag says Z so 3:08s it is. It didn't feel like 2:73s so this confirms it.
Thanks!!
