Ok, so this might seem like a stupid question, but here goes. I've been wondering if the gears from an f-150 or ranger with an 8.8 will work in my mustang's 8.8. I've been doing a little bit of googling and the info is tough to come across, but so far it looks like "yes". I want to confirm this before I try, though. The big thing I'm worried about is the spline count. This site says that gears will interchange regardless of spline count, but differentials will not. I would like to confirm this. Also, would I be able to use the limited slip from one of these trucks provided it's from a truck with 28 spline axles? That site lists which Rangers to look for in that regard but I haven't been able to find similar information regarding F-150s. Any help would be appreciated, but if this is a stupid question feel free to flame.
