I'm looking for a rear posi unit or a locker for my 1994 c2500 7.4l automatic. The rear axle doesn't have an ID tag on it like I'm used to seeing, I've searched and searched online and I have no clue what i have, what to get or where to start. A friend suggested Aussie Locker but I'm not sure they make a product that fits. If you can kindly help me out it would be much appreciated!

I'm down for saving tires! I've found the Truetrac online and I keep seeing 9.5", 10.5" and 11.5". I had no idea there were so many options in old Chevy trucks

So the other info I need is my ring gear ratio, axle spline count, and rung gear diameter, correct? And way to ID that without removing the cover? It's an 8lug truck if that matters.
