I recently went through something similar... PO installed 71-72 components onto my 67 with drop spindles to match those 71-72 ball joints and tie rod ends. After ordering and installing the WRONG upper/lower ball joints for a 67, I discovered they will not work with the spindle which was requiring 71-72 parts.

MOOG parts for the two different model ranges.

.........upper lower outer inner upper shaft kit lower shaft kit
67-70 K6024 K6023 .ES350L ES370R K6098 K6147
71-72 K6124 K6117T ES415RL ES403L K6098 K6147


The table above lists out the ball joint, tie rod and a-arm shaft MOOG part numbers for 67-70 and 71-72. Note that the shaft kits are identical.
