Well I started with the drivers side. All went well. That side is done. Then the passengers side. Came apart fine. I put the old spindle back on. Bolted upper in to place. Threaded lower nut on. Got down about 1/2", and it started to spin. Seemed like I was turning it to long a time. Took a look, and the nut hadn't moved. I did manage to get the nut back off. The lower was pressed on. I had to drill it out. I looked around town, but they don't have the complete assembly like speedway motors does. All I could find was just the ball joint.. On speedway I found this Pinto-Mustang II Ball Joint - Speedway Motors, America's Oldest Speed Shop
