Ac compressor with air gap intake

Classic gets their kits for installing the Sanden compressor from Bouchillon (has their name stamped right on the brackets) for use with factory AC crank pulley and Water pump pulley. I just installed one on my 70 dart with a small block. I used an LD4B Edelbrock manifold, which cannot be used with the factory compressor. I had to grind a little clearance on edge of the Thermostat housing and on one of the "fins" on the snout of the water pump (for the belt). No big deal and not very much material removed. PM if you need photos of those 2 spots. This kit will not work with the offset thermostat housing for later LA motors. Post a picture of your manifold.
