Another question!

[alabama mike]

I have gotten my 65 c60 in pretty good running shape, and have hauled a few loads with it and am quite happy with the old truck, I've started the body work and will try to have it painted before the summers over.

But I have gotten this truck I have been searching the internet for any and all information about the older c60 and I ran across a Green C50 that was made into a pickup,

I would LOVE to do this to a 64/65/66 c60 but my question would concern the rear end, My current truck does about 55 mph with the rear end that's in it, and for what I use the truck for that's fine, but If I built a "big" pickup I would want to be able to travel interstate speeds, is there a differential that will interchange with the older c60 that would give it better speed? I don't see the need for a 2 speed in a pickup since I probably would never haul anything other that me, the wife and my dog. The smaller c10 stuff is easy, I don't have enough knowledge about the bigger stuff and hadn't been able to find it on the net. anybody got any ideas?
