As this has been going on, I've read the whole thing. But I don't think you ever said why you decided to go with NEW cast arms. It's undoubtedly easier, but also more expensive, and you could have upgraded the bushings by press-out-and-replace. Tell us your thoughts.
Partly due to time/downtime if something went wrong,,, and also because I couldn't get any accurate info that aftermarket cast arms are truely available for the Gen 2. Moog SUPPOSEDLY sells cast arms for the gen 1. Rig's and I at one time talked about the differences between the Gen 1 and Gen 2 rear arms,,, but nothing was proven 100% to work, (cross over).
As far as pressing the bushings... I didn't find any info on the larger front bushings for the lower control arm being available,,, other than in urethane from a place "across the pond".
The other 2 metal bushings are available from sources... but quality seemed a bit suspect. Not to mention that pressing them out can be a bit tricky. Supposedly, (somewhere), ... some have cracked the eye on the control arm trying to press the metal bushings out. Also, the metal bushings are slightly offset to one side in the eye. Improper installation will cause fitment issues... and in the long term, (if a person manages to still get the control arm in), premature wear on the replacement bushings.
So in the end... instead of trying to attempt aftermarket Gen 1 arms for half the price of factory arms, (I paid roughly $550 shipped for both... I'd have to find the receipt to verify),,, or having the extra labor and potential of having something go wrong, (meaning more downtime),,, of pressing bushings... I just went for complete original arms.
