I bought the kit for the 66 from CSRP and it was a simple install with great directions for step by step guidance. A GREAT BARGAIN AT $524. EVERYTHING you will need in 1 box, And EVERYTHING is NEW.
You will not be able to beat the price by using used parts from donor cars. Figure you will be buying worn out parts that will need to be rebuilt or replaced. Then add in what you think your time and gas money is worth running around to Pick and Pull.
I went to a local junkyard and they told me $250 for the for the Granada spindles, calipers and discs. They would pull the parts though.
Then figure I would need to rebuild, resurface and install new bearings. Oh and dont forget about the MASTER CYLINDER AND PROPORTIONING VALVE.
