Made in USA. This new Criss Cross Apple Sauce SD7B10 Compressor Fitting Kit (Machine Finish) - 045000 solves an age-old problem for those of us that are blessed with OCD. If you know, you know. If you have used a SD7 A/C compressor on a serpentine belt front drive kit, you may have discovered that the #8 port that connects to the condenser is behind the #10 port that connects to the evaporator. This creates a situation where the back hose on the compressor goes to the front of the car and the front hose on the compressor goes to the back of the engine compartment and the two hoses have to cross each other. After sharing our frustration with our good friend Dean Livermore at Hot Rods By Dean in Phoenix, he set about to create this compressor block that rectifies the hose orientation by crossing the passages inside the block. We call it the Criss Cross Apple Sauce Compressor Fitting Kit. Say goodbye to crossed hoses and say hello to a neat solution for plumbing your SD7 Compressor. Works best on systems that orient the compressor with the ports coming out the side rather than the top. Vintage Air Front Runner kits and Holley Mid Mount Serpentine kits mount their compressors in this manner and there may be other manufactures that do so as well. If you need a front drive kit, call us at our sister company Affordable Street Rods 620-792-2836 and the staff there will be glad to help you choose one that is perfect for your application.
