Overview:

Holley's Mid-Mount accessory drives are now available for your small block Chevrolet engines! The revolutionary system does what no other accessory bracket system has done… GETS RID OF THE BRACKETS! The Mid-Mount complete accessory system has all accessories pulled in tighter than other accessory drives. At the heart of the system is a "bracketless" design (Patent Pending), where the accessories bolt directly to the water pump for a clean, integrated form. The design offers superb engine visibility to show off your horsepower, not your accessories. The Holley designed alternator is just as innovative. This premium alternator utilizes 6-phase technology as found on the C7 Corvette. The water pump also shares its design efficiencies with that of the C7 Corvette. The compact and reliable SD7 A/C compressor and Type II P/S pump with baffled reservoir are also integrated. The water pump design incorporates optional side or top heater ports. The top thermostat bypass and heater ports are recessed into the manifold. So if you don't need them, you don't see them! When we say "complete", we mean complete. The Mid-mount system comes with everything you need. All accessories are included; the water pump, A/C compressor, Alternator, and P/S pump with reservoir. All pulleys and the belt are supplied. Even A/C line adapter, heater hose adapters, power steering to -6 AN hardline, and the alternator plug/harness are included. Easy assembly was a priority during the entire development of this accessory solution. Color graphical instructions walk you through every step of the ultra-easy installation.

Nice small wallet, almost too small, ID pocket not very useful
Color: Two Tone - Cobalt Blue
It looks really nice and well-made, but the ID windowed pocket is too tight to easily get out your ID then you need to use it. No one lets you keep your ID in the wallet, so why bother with a clear window pocket?

Lots of Space for a Small Bag
Colorful and great! All Haven't been without a Coach bag since the early 1970s. I'm usually not fond of the signature bags, but this one is striking. Of course it is well made. The bag has two compartments that are large enough for checkbook & phone. It has 8 card holders, 2 smaller places for business & library cards, a place for folding money, a zipper middle compartment and 3 flat compartments for receipts, notes, etc that are all packed into a cool small bag. It comes with both a crossbody metal strap and a leather wrist strap.dd Often, I've found Coach credit card holders inside their bags are too small for credit cards. This bag has larger cardholders. Overall, I give it an A+.
