O.k., so i've finally located an Eaton HO72 differential so i can swap it out with mine in my 54 3/4 ton. I have the 4.57 gears. As i understood it the 67-72 Eaton H052-72's for 3/4 tons either had 4.10 or 4.57 gears. This guy thought it had 4.10 gears but upon looking closer it has 4.11 gears. After looking it up i think the 1 ton HO72's came with 4.11 gears. Would this still work in my 3/4 ton as an easy Differential swap? and if so would i still gain nearly as much cruising speed?

Thanks for the input.
