i have noticed f-150s arent using the 31 spline 8.8. it seems they havent been since around 2000 or so. what are they using now? it looks like a dana shape to the cover but i really dont know.

My guess would be the 9.75", is this it?

good idea, lincoln lock the dif on a DD truck. its too new and too nice to do that to. he was really hoping for a quiet locker but a locker is defiantly better than welded since it will be on the street. he does a lot of off road for work too.
