Overview:

Holley's Premium 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. Among the many swap friendly features are bottom heater outlets for clearance in tight applications. 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 Mid-Mount drive completes Holley's trilogy of accessory solutions giving a third option compared to the High and Low-Mount previously released. All three accessory solutions are for LS engines. 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, P/S pump with reservoir, and an SFI certified damper w/hard anodized billet crank pulley. All pulleys and the belt are supplied. Even 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. The Premium Mid-Mount system comes with dress up pulley covers and an SFI certified damper. Partnered with this damper is a billet 6061-T6 aluminum hard anodized crank pulley. This system is ready for the racetrack if you want to play or just be ready for anything on the street.

Hard Nose Bridge
Color: Blue-black
They seem like nice goggles. I would echo what others have said: The nose bridge is made of hard plastic with two little bumps on each side (conceivably to snap the lens into the nose bridge) that very well may press into your nose, making the goggles uncomfortable to wear. I would look for a pair with a soft nose bridge. I previously owned a pair of Aegend swim goggles with a soft nose bridge that I liked.

Totally worth the price!
Color: Lagoon, Style: 2 Blocks
These are great blocks! They are soft yet supportive. Used for yoga, Pilates and on the sits-bones when meditating. All purpose, perfect size, cute, calm color. I have two sets, I like them so much; one for the house and one in the gym.

Light weight and good support

Highly Recommend Gaiam Yoga Blocks The Gaiam yoga blocks are excellent quality and a must-have for any yoga practice. They’re lightweight yet very supportive, making it easy to maintain proper alignment and balance in a variety of poses. The foam is firm but comfortable, with a non-slip surface that stays in place during practice. These blocks are especially helpful for stretching, improving flexibility, and modifying poses, whether you’re a beginner or more experienced yogi. They’re durable, easy to clean, and hold their shape well over time. Overall, Gaiam yoga blocks offer great value and reliability. I would definitely recommend them to anyone looking to enhance their yoga or stretching routine. 🧘‍♀️✨
