            Nice addition and looks nice .

            Had to replace differential cover due to I guess hitting a low spot in my travels bending the cover plate thus leaking fluid . So I ordered the chrome version . Impressive indeed , very thick metal and easy to install .

            They cost the same as basic stock rotors. But these look better and stop better then the originals. Very easy to install.

            Cover

            After noticing that the rear cover was covered in dirt and oil I wanted something better looking for the rear end. I couldn't beat this deal for a new cover, gasket and bolts all in one package. Now for new Hijacker shocks and paint the axles when I get it back up on the rack.

            Ordered this to replace the damaged and leaking cover on my '00 Lincoln Town Car. Heavy duty, great fit and finish! Gasket worked excellent, no leaks and no need to use RTV. Shipping to Canada was quick. 5 Stars! Highly recommend!

            I just bought my 05 GT, I did not realize it had a leak on the rear cover so I decided to buy this cover and it was an excellent choice for the price. It took me more than an hour cause it was just me and I like to take my time when doing something to my ponys. Thanks American Muscle. Always with best prices an quality.

            Great price, quality product

            This is the second chrome cover I've purchased from AM. Like the first, it's a beautifully polished finish, with all new bolts and a solid paper gasket. It's about 3 times the thickness of the factory aluminum cover. Just make sure to wet the gasket before install and you're golden! Er, I mean: you're chrome! Note: the owners manual states 75w90 for "regular duty" and 75w140 for "heavy duty". I highly recommend fully-synthetic 75w140 for all Mustang rearends. I've experienced great performance with Mobil 1 75w140.

            Great product for the buck!

            I was leaking differential fluid so I had to change the gasket. This cover comes with the gasket and bolts also for not much more than you would normally pay for a gasket alone. It took me a couple of hours to install and it fits and looks great. Good product I highly recommend it. With free shipping there is nowhere else on the entire internet where you can get a deal like this! Great job American Muscle!
