66’ C20

Moog K680 upper ball joint not fitting, to big at base. Bolted in and will not seat on upper control arm. Stays about 1/8 off control arm.
Have four of them and none will fit 64 or 66 C20 front upper control arms.

Others have this problem, purchased sets four months apart.

Will call Moog.

Additional information, their seems to be two different versions of this ball joint.
Did purchase another one from a different source, and it fits.
Photos of both below.
- The lower one in photo1 and 2, along with photo3 are the ones that fit.
- The upper one in photo 1 and 2, along with photo 4 do not fit.

Vender is replacing the ones that do not fit, hope the new one fit. At least now know which do not fit.
