    Several reviews mention that this product comes with bolts and a gasket, although the description does not. Is that still the case or will these items need to be purchased separately?

    The stock covered takes just a little bit over two quarts of fluid. You say three quarts ,does this new cover change the amount or is it the same as ?

      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.

      perfect fit

      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 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!

      Looks sharp!

      Bought this as part of a complete rear-end rebuild on a 1995 GT. Really looks good- can be seen under the car. It's a good way of letting everyone know that you've got upgraded gears! The gasket that came with this was also better quality than the one in the gasket kit.

      Sweet rear end!

      Installed my chrome differential cover in a couple of hours (due to difficulties with removing the fill plug). New cover came with all new bolts and gasket that fit perfectly. Filled differential with Royal Purple and had No leaks to deal with. Cover looks great and is stronger than original.

      Looks cool

      Makes rear end look shiny and new. Maybe it makes my rear end more stiff but I can't tell for sure. If I had more loot, I woulda bought the one with the drain/fill holes and cool strong look. But for 30 bucks, ya can't beat it!
