MOOG products good quality?

Here we go... moog vs delphi vs factory. Let me preface by saying that i believe the parts i removed from these arms are factory. I know i cant prove it. I was not at the factory in 73 and i haven't owned the parts my entire life. But i have no reason to lie and all tbe signs point to to it.. tell me.. who eber chaned bJ's before doing a brake job like ever??? And the car has favtory brakes.. Let me also day that you guys were right and i was wrong. No way around not welding the BJ's in... IF.. i want to re use these arms and use moog or delphi.. let me also say that i re threaded in the bj's i took out and they thread in tight. I dont have a caliper but they are slightly larger than the aftermarket.
