I have a '72 and just went through this, went to three different auto parts stores. All the upper ball joints I tried did NOT go through the spindle far enough to get the nut past the cotter pin hole on the originals or the new drop spindles.

Then I went to NAPA and bought the NAPA brand ball joints from them that fit perfectly.

I think there are different ball joints made by different companies that try to say they are for our trucks but just don't have the right measurements. They try to be the one set for all but just don't cut it and end up being junk and causing us a lot of misery.

Don't go cheap! Get the expensive ones and you will be happy.
