As for the install, it is a 20 hour job and requires only standard hand tools. The system for your 70 includes a new factory replacment controller. The hose all connect to the factory Astro vents and a new center vent is included.
For compressor mounting, We could set you up with the SD7 compressor in the kit at no extra charge, and then you could do the inexpensive March Mid Mount Kit which would give you a serpentine set up including all the pulleys and brackets and would put the compressor on the lower pass side of the engine. The entire bracket and pulley kit is only $700 and since your getting the compressor in the kit anyway, it is the perfect time.
