MSD's Ready-to-Run Pro-Billet Distributors for Chrysler engines are the perfect upgrade from breaker points or weak electronic ignitions. These distributors feature a maintenance-free magnetic pick-up that accurately triggers the built-in powerful ignition module. This module produces a high-output spark which improves combustion in the cylinder, resulting in quick starts, a smooth idle and great performance. Just beneath the race rotor is a mechanical advance assembly so a timing curve can easily be tailored to match your application. The QPQ coated shaft is guided by a sealed ball bearing assembly for stability and endurance while a vacuum advance canister helps increase economy on those long cruises. The Ready-to-Run Distributors are also a breeze to install. Simply drop it in the engine and connect three wires and you're ready-to-run to your favourite cruise! The front engine mount models are designed in a special small diameter housing to clear aftermarket heads and valve covers. A matching harness with a 3-pin Weathertight connector is supplied.

They are using different/cheaper shredded foam then they were 1 year ago
Color: Memory Pillow, Size: Standard, Color: Memory Pillow, Size: Standard
The shredded foam used last year was really nice and soft and even firm to a point where your head is supported perfectly while you sleep. now the 2 extra pillows I received this weekend have completely different shredded foam which seems to be cheaper. Also when you unzip the pillow cover and get to the part where you can unzip the other cover where the foam is no longer is there. so they are using cheaper shredded foam and a cheaper cover to where the foam is and you can no longer unzip the second cover to see the foam. but I can easily tell that they are using different and cheaper foam which isn't true memory foam. their new blend is too fluffy and the pillows are floppy and too soft. the old ones i bought 1 year ago are heavy pillows that are true memory foam which your head molds into perfectly and are amazing. these new ones they are making aren't worth it. In one picture you can see the cover with different colored cheap foam and the other picture with the green and white thick premium quality shredded memory foam. The other pictures show how the old ones are thick and firm and moldable for you head and the other 2 are floppy because they use cheaper shredded foam. They need to use the shredded foam they used last year! it was really good! Now they are not true memory foam pillows anymore due to changing from premium shredded foam to cheap shredded foam.
