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.

Natural Dunlop Latex Topper Has Multiple Uses
Size: Twin XL 2"
This is a well made, high quality, 2” thick piece of all-natural latex. You can use it on top of any bed to provide a nice, comfortable mattress topper that has a medium-firm feel to it. It gives good support for those who sleep on their back and on their sides. The latex topper springs back and sleeps cooler than memory foam toppers, which compress and generally sleep hot. Latex toppers cost more upfront than memory foam toppers, but they can last twice as long. I built a custom-made all-natural latex bed that was too soft and didn’t provide enough support. I removed a 2” thick piece of ultra soft (#14) Talalay latex inside the bed and replaced it with this 2” thick piece of Dunlop latex for more support. I then used the Talalay latex on top as a mattress topper and now my bed is perfect! Once you’ve slept on all- natural latex, you’ll never want to go back to artificial memory foam.

Discovered latex and thrilled
Size: Queen
Bought a Beautyrest mattress in late 2021 that now is uncomfortable and has dips. Beautyrest would reject the 10 year warranty due to a single stain on mattress (based on their policy), so I didn't even bother. So, I pondered if I should order a new one and which one. In the process I found out latex toppers may save the day. Talatex medium firm mattress in queen size was received within a week and a half and installed on top of existing Beautyrest mattress. Since then, no pain in hips, no sweating at night, no neck problems. My daughter tested it one night with me, and since then wants to sleep on my bed and not hers, so this is really reviewed by two people. Excellent product!! Has a bounce but you don't sink in it (two mattresses ago, I had a 13" high end high density visco elastic memory foam mattress where sinking into it happened). When I can afford, I will buy a 4" latex topper firm and install that under the existing 2" Talatex medium firm over a slatted base. I'll do away completely w/ the mattress I'm using now.
