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 doneโ€ฆ 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
A little small but my dog loved them. Does not hold up to a shredder though. Perfect for typical toy lovers

None of the stuffing pulled out
I have 3 dogs. 1 is very gentle w/ stuffed toys. 1 is new to us and very anxious and kept stealing things like water bottles to gnaw on. And 1 destroys every stuffed toy we have ever brought into the house. We bought these for the anxious one. She was recently adopted and very people shy and afraid of the world around her. She doesn't know how to play with people and she's terrified if you try to throw a ball or if you squeak a squeaker, but we also needed something durable enough for her chewing that would be safe for her and could also withstand the toy destroyer possibly getting hold of it. They've been playing with these for a few months now and the most damage is that some of the rope necks are a bit frayed and a lot of the fuzz on the outside is gone, but none of them have been torn open. And the squeakers are in there in a way that it's hard to make them squeak if not doing so intentionally. The 1 dog can have plush toys again, the 1 dog can gnaw and chew to reduce her anxiety and the 3rd can chew and attack it without me having to clean up stuffing all the time

Very durable
Color: 3 Pack Donkey Giraffe Dog
For some reason I thought they would be a little bigger but I have to say they are very durable. My Saint Bernard has not shredded them to pieces yet. Normally the toys last a day or two but he still has them after 3 weeks. ๐Ÿ‘
