Well over the weekend I found a spare rearend for my 1 ton,I think it is a 1 ton rear(5.11).But what I'd like to know is if there are any numbers I can look at on it to see if it's a 4.56 (3\4 ton)rear?I tried to turn it but I think both brakes are stuck.And if it is a 4.56 and I want to change my gearing can I put the gears from it in my 1 to axle?
