60 1/2ton rear end question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

What rear ends did the 60 1/2 tons come with? I don't believe the standard unit was a 10 bolt DANA 44 but rather a GM 10 bolt but which one?
I believe the truck I just picked up has a 3.90 posi gear in it but I want to go to something lower. I'm running a 307" SBC and a 3 speed stick. I know the optional gear was a 3.37 and ClassicParts carries them but I'm not sure if they will work with the posi unit. Help me firgure out my options. The Richmond web site does not show which GM 10 came in a 60 1/2 ton 2WD. Does anybody know which one it is? Thanks.
