Any clues here?? I've called St. Charles and they weren't able to decode the VIN. I need to replace the ring and pinion and pretty much everything else back there, but I will need to know the ratio before I order.

And yes, I know the REAL way to find out is to drop the cover and start counting teeth, but I was hoping that someone here would have some knowledge of this upfront.

1992 Isuzu Rodeo, newly rebuilt 3.1L v6 and rear diff; clear corners, bumper and tails; Aiwa MP3 head unit; Infinity Perfect 10.1 sub; Polk seperates; Sony cross and amps.
Next projects -- New paint, tint, billet grill, nerf bars.
