Overview:

Holley's 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. 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. This 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.

This jean jacket is super cute comfortable and I get a lot of compliments😍🤩
Size: Large, Color: Medium Blue Vintage, Size: Large, Color: Medium Blue Vintage
I absolutely love this denim jacket—it’s become my new go-to layering piece for everything from casual errands to date nights! As a busy mom who needs clothes that can keep up with my day without sacrificing style, this one checks all the boxes. The medium-wash blue denim has that perfect lived-in feel right out of the box, with just the right amount of structure while still being soft and comfortable against the skin. The fit is fantastic—it’s cropped just enough to flatter without feeling too short, hitting right at the waist so it pairs beautifully with high-waisted jeans, leggings, or even flowy dresses. I love the classic button-front design and the chest pockets that add a touch of authentic detail without being bulky. The sleeves are nicely tailored too, with enough room to roll them up for a more relaxed vibe or wear them down for polish. It’s surprisingly versatile for all seasons: throw it over a basic tank or tee in warmer weather, or layer it over a cozy sweater when the evenings get cooler. What really stands out is the quality. The fabric feels sturdy and well-made, with reinforced stitching that makes me confident it’ll hold up through countless washes and wears. No fraying or fading after a few cycles so far, which is huge for something I reach for multiple times a week. It’s also got a nice subtle stretch that moves with you, making it ideal for long days chasing kids or sitting at a desk. I’ve styled it with everything from sneakers and mom jeans for school drop-off to boots and a cute top for church or a night out, and it always elevates the look without trying too hard. If you’re looking for a timeless denim jacket that feels fresh and modern, this is the one! It’s flattering on real bodies (curves and all), easy to care for, and instantly makes any outfit feel more put-together. I’ve already recommended it to several friends, and I can’t imagine my closet without it now.

Great jacket for the price!
Size: XX-Large, Color: White
The denim jacket has a nice relaxed fit without feeling too baggy and it looks great doing it. There's just enough elastic for the jacket to stretch a little without losing its shape. The color's accurate and it's hard to beat the price so I've no notes!

I bought these shoes with plans to take photos with my son for Christmas. It was last minute and these really impressed. Other places were charges $20+ more than the rate here on Amazon. They fit true to size. They Look super nice and sleek and got the job done.
