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.

Small in size
Color: Grey
Very small, picture makes it look much larger than it is. Seemed more appropriate for a cat, and 6 month puppy figured it out in under 1 min. Not very challenging.

Extremely good quality. Soft ... SIZE UP if you want a looser fit. It is not "form fitting, or snug, but no extra. I am 5'5 190# 60 years old. This ... an XL will go to my daughter. I will be getting another 1-2 sizes up. We'll worth it!

best enrichment activities and a mental outlet
Color: Blue
I use this puzzle toy regularly with my two dogs, and it’s been a great way to provide mental stimulation while slowing down treat time. The sliding compartments are easy for dogs to understand but still challenging enough to keep them engaged. They quickly learned to use their noses and paws to uncover the hidden treats. It works well as both a slow feeder and a boredom buster, especially on days when outdoor activity is limited. The toy feels sturdy and stays in place during use, even when both dogs are actively working through it. I like that it encourages problem-solving without being overly frustrating. This is best for dogs who enjoy enrichment activities and need a mental outlet. For very strong chewers, supervision is still important, but as an interactive feeder and skill-building toy, it’s been a useful addition to our routine.
