Exactly, you can speculate until the cows come home and still have a 12-bolt that's a quart low with a posi that's on the verge of self destruction...Take a pic of the cover and post it, right before you go ahead and remove that cover to see what you have. All to often there will be fragments of busted thrust washers, pieces of pinion and or ring gear teeth, or nothing at all...Rear ends are probably the most neglected component in a trucks drive train. All three of my 12-bolts have "60" cast in the housing, but I dont think the C/20's got 12-bolt's. They either got Dana 60's or the HO72's. Once you've determined what rear you have go ahead and splurge for a couple of cover gaskets. I know many never use them but there just isn't a good reason not to and several reasons why you should.
