Early Vs. Later Lower Ball Joint Issues

While "in there", could you tell me which side that tapped hole is in your 10" drum spindle - fwd or aft side? I can't tell in your photo. The reason I ask is that I mixed up the left and right spindles in my 1965 Dart after painting and couldn't find any info, nor make out the PN's stamped on the forgings. The spindles are not exactly symmetrical, so it matters.

I have it assembled now and seemed only way worked so the steering arm angled properly to the steering linkage. But, that differed from my memory of disassembly and what I think I made out in the PN's. The reason I remember disassembly is that I didn't know one hole was tapped and beat the bolt out, thinking it was stuck in rust (idiot). No damage since those threads aren't essential (nut behind them) and might have been there just to speed factory assembly.
Yeah, They're both "Aft" The Threaded One is the Lower of the two also... (Photo's of "Drivers-Side")
