Evenin' all.. About to order parts for my 2011 Ranger 5sp / 4.10 gear set. I'm going to replace the 4.10 gears with 3.55 as well as install a limited slip. I've checked the VIN on the site: http://services.forddirect.fordvehic...icker.pdf?vin=(insert VIN here) but can't get any info there regarding the axle...whether it's a 28 or 31 spline. The truck has an 8.8 rear end and rear discs with 4.10 gears....but can anyone give me information regarding with the splines? 28 or 31..??
