OEM upper ball joints
What's the history on round top and flat top upper ball joints used in the 67, 68, 69, time frame ?
My Aug 68 1st week of production Chevelle has round top, Gradys Nov 68 built, 69 Nova were flat, and the older NOS upper arms I used on the last COPO build were also flat.
Was it just a vendor thing ?
