I recall the 71-72 vs 73-87 spindle differences were the TRE's. Drum brake spindles use different UBJ's/LBJ's vs disc brake spindles. I've always used the 73-87 platform when modding the front suspension so I have no knowledge of the 71-72 model specific parts. I swapped things to whatever the 73-87 spindles required (arms/steering/etc).

Thanks,

It appears from my research that the LOWER ball joint is the same from 1971-1986 ('87 R10 also). But the UPPER ball joint is specific to the 71-72 and then a different one for the 73-87.
I would think that mounting the UPPER ball joint to the underside of the upper arm will give you a slight increase in ball joint height (it moves the pivot point of the ball about 1/2" to 5/8") vertically referenced to the plane of the arm. I my head, that tells me you would get some benefit similar to a taller ball joint...
