Have 95 dually rear end with 3.73 ratio available to purchase. Have 77 GMC crew cab dually that needs new rear end. Prior owner put in one that is to narrow. Have a bunch of 4.10's from the correct year (up till 89 or 91) available, but the 3.73 is a better ratio. Question is, is the newer year (95) axle a direct bolt in or is some major tweeking going to be necessary? Posted same question on 6.2 site, but no replys yet.
