So I’ve been looking into the 8.8 rear end swap and came across a really good deal for a rear end of what looks to be a 2013 track pack. I know that some 2011’s and up have the correct flange from the factory, but since the Track Pack has upgraded parts in the diff, I’m not sure if the flange is different or not. So does anyone know if the flange from the Track Pack is compatible, or have any experience or knowledge with swapping the rear end from a 2011+? Also, I’m not sure 100% if this is a track pack car, I’m waiting for the guy to send me pics of the rear end to verify for myself since it doesn’t seem like he know what he has. I’m just curious if the rear end will swap in the case that it is.
