Just keep in mind the 60 is a little heavier and the tire sizes maybe different. Tire size effects rpm. If you drive the 60 physically measure its tires. Note the rpms at highway and other speeds, so you can compare with your vehicle and tire sizes. Tire manufacturers advertised size isnt correct. Checkout an rpm calculator to see your current setup and compare to what you're considering. I usually make a chart. Reference each gear ratio 1st thru 4th or 5th. Include low range in the various gears too. Especially if you wheel. Do your trans because you know what you like and what it's lacking, and then do the same for the other trans and tcase. Look at the ratios and compare. When you change diff gearing it's going to effect low range, along with highway characteristics. The split case is interesting because there are gearing options available for a price.
