    I would very much like to change the ring & pinion gears in the rear end of my 1969 C20. I don't like the extremely low gears that are in it now. From what I've read, I think that it is an Eaton HO52, but would like to confirm that. Truck has a 250 six, with 3 spd transmission. Differential has 10 bolts. Axles are 8 lug. The gears are very low. I'm assuming 4:56 or 4:57, but don't know for sure. Does this sound like an HO52? I can't find gear sets for this in the Classic parts catalog, (nor any others where I've looked). I really like driving the truck except for the low low gearing. Can any of you folks point help educate me or point me in the right direction? I'll much appreciate it. I've fixed lots of things on this truck since I bought it, and now I just want to be able to enjoy it. Thanks
