Hello everyone like it says in the title I'm looking for a rear differential cover for my truck I owned two Chevys before this I don't understand why it's so hard to find the rear differential cover for this truck I had to call the dealer and have them order me one I wanted an aftermarket one that had a higher fluid capacity the dealer wants $100 for the back 120 for the front I have 125,000 miles on my truck so I figure it's time to change it out my question is why when I call Napa they have no clue what a American axle 14 bolt 10.5 I found an ATS cover holds more fluid and I want to know if it would fit my truck or not it's it's for the Cummins thx guys any help will be appreciated specs my truck is 2006 2500 hemi 4wd quad cab slt model thx
