Overview:

Holley's Mid-Mount accessory drives are now available for your big 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.

Exactly what I needed!
Color: Natural, Size: 6 Panels
My main use for this may be different than most people. I was taking care of some kittens and wanted to keep them away from sensitive areas of the living room (wires, home theater equipment, etc.). At first I stacked some boxes around, which was rather ugly and ineffective (made it harder for ME to get around more than anything else). I went online looking for a better solution and found this room divider. This did the trick! Finally I could have a stress-free time while the kittens were running around, and with something that actually improved the look of the room too. The divider itself is put together very well. The hinges actually fold both ways, so you get some versatile configuration options. It is lightweight and easy to move around, making it very easy to stash out of the way when not in use. I was so pleased that I went and bought 2 of the smaller 4-panel dividers as well, to use in a different area.

UNhappy Customer!
Color: Natural, Size: 6 Panels
Quite honestly I dont normally give poor reviews. I dont normally get poorly made products from Amazon but this time has changed things for me. I will order very little and will especially be mindful of anything made in China! This divider arrived in an intact but wet box. It took me nearly 20 minutes to get it to unfold. The two outside panels flipped out freely but for some reason I had to work to get the other panels to unfold. When it did open, the second panel was clearly damaged. I proceeded to prepare it for return, taped it up securely, requested and received a return label and traveled to the UPS store to return. Wouldn't you know it...UPS shipping charges were $154.00!!! More than I paid for this inferior product. So, if I return on my dollar and hope it makes it to the appointed destination and receive $151.99 for the return cost, I'm out $154.00 and no product to show for it! Its amazing how sellers come up with ways to unload their junk and then prevent satisfied customers by making them pay for the return shipping costs. I opted to keep the junk and consider it a lesson learned. What a scam!
