Our Hydropower hydraulic brake assist power booster fits 1964-66 Chevy Chevelle, Malibu and El Camino and generates up to 1800psi of line pressure to the brake calipers. It is fitted with a POL master cylinder and proportioning valve. This kit is powered by hydraulic line pressure from the power steering pump. Firewall and valve cover clearance is equivalent to a 7" diameter vacuum booster. The firewall brackets are correct for 64-66 GM A-body applications.

The average power steering pump puts out from 800psi to 1400psi line pressure. The Hydropower® uses this to convert to pressure to apply against the master cylinder. This greatly improves stopping performance and driver feedback. These hydraulic power boosters can be easily installed on an existing vacuum booster vehicle or used to convert a manual brake setup to power with ordinary hand tools and average mechanical ability.

Fits: 1964 1965 1966 Chevy Chevelle, Malibu, El Camino, Buick Skylark, Oldsmobile Cutlass, GM A Body

Preassembled Kit includes:
• Hydraulic brake assist power booster
• 1.00" bore POL master cylinder
• POL proportioning valve, bracket and lines (disc brakes)
• Firewall Mounting brackets

These are remanufactured Hydropower units. Hydropower® is a registered trademark of the Robert Corporation

Good fit, good quality, great price
Size: 16"-16.5" Neck 32"-33" Sleeve, Color: Carbon
I ordered a few of these in different patterns. They fit great (I used to be a L/XL, now I'm down to a M/L). The price is a third of similar shirts from other Men's stores and fit the same. They look great with jeans or slacks, tucked or untucked, with or without a jacket.

Nice, but...
Size: 16"-16.5" Neck 32"-33" Sleeve, Color: Tulip
The shirt is nice and fits well. However, it's not slim fit. It's just regular fit and "slim fit" should be removed from the description.

Stylish shirt
Size: 14"-14.5" Neck 32"-33" Sleeve, Color: Ash Green
Perfect fit and size, as promoted. The quality and feel (comfort) are nice. The color is a little lighter than what I could see on the screen, but I liked it. The shirt is not too thin or thick.
