This is a complete and nearly 100% bolt in Air conditioning kit for 1955 or 1956 Buick Century and Specials. It uses a Modern Sanden 508 style air conditioning pump (and brackets to mount it on your 322 nailhead), a modern evaporator, a modern aluminum condenser, a trinary switch that controls the pump and an electric fan that sits behind the condenser, and includes all lines and hardware to install! All hoses are included and most AC hoses are crimped- you only need to cut and crimp two hoses to get this sytem ready to charge. You will be shocked ar how complete this kit is- it is not a universal kit shoehorned into these Buicks. These parts are designed and built from the ground up specifically for your 56 Buick Roadmaster / Super.
 
The firewall mounted evaporator and box bolt up to your factory bolt holes on the passenger side firewall and your factory blower motor housing attaches to it, so the rest of your heater, blower motor controls and everything under your dash are completely unaffected. It gives MORE clearance than a factory non air conditioning box on the engine side. So it works great for original engines or even swaps with larger engines. The housing is made out of Plasma CNC cut 14 gauge steel, mig welded together, with insulation on the inside to avoid heat soak. 
 
The Condenser comes with mounting brackets that bolt to the front side of your inner fenders behind the grill. the condenser is then screwed to those brackets. absolutely no cutting or modifications to your car. the 14" electric fan fits behind the condenser, out of sight, and is controlled by a trinary switch that cycles it on and off so it is only on when it is needed. It draws about 9 amps, moves a fair amount of air, and is relatively quiet.
