So, I am guessing you bought the 71-72 spindles so that you did not have to changes ball joints and/or tie rod ends.

We are discussing this in PM's now so I wanted to put it here as well....

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).
