I just had a Dana 60 rear put into my '72 K20 with 3.54 gears. At the same time I had the Dana 44 front changed to 3.54. Wow! What a nice combination! I have a pretty tall tire (265/75/16) and it rolls right with highway traffic and feels great. BTW, at 70 mph, my speedo reads 57 (need to update my speedo gearing). I had contemplated the Gear Vendor solution but am SUPER pleased with the 3.54 gears. As an added bonus, the rear swap finally resolved a vibration issue the truck has had.
