Thanks guys!!
Yea i've been driving it quite a bit, hauling equipment, and friends around on the weekends.
I've been working it pretty hard to get the rings to seat, but with the pump up all the time i'm still averaging 12.5mpg which i don't think is bad at all compared to the 5mpg i got with the 454 2wd empty!
It's a blast to drive, except the spooled rear end, that has to go!
Looking for a good affordable locker, any recommendations??
I'm working on getting a video up soon, but harvest really has me tied up right now so I apologize..
