It looks like I might have to put a later model rear axle under my '62 K20 to get the gear ratio I want. I have an Eaton HO70 with 4.56 gears, I know I can get 4.11s, but that's not gonna be good enough, I want better mpgs. I'm pretty sure the Dana 44 front end will be a lot easier to find a set of 3.73s for.

My concern is, will my stock, three piece, 8 lug wheels fit on a later model 3/4 ton rear end? With all the money I spent on tires and tubes, etc. I don't want to throw them away.

Thanks, Brad
