Figured I'd make an update: after
5 months+ no issues on the A-arms or the rubber bushings
Spare spindle is holding up very well too.
Now that the kid's have started back to school the Spiderbox won't be beat-up for endless hrs. each day. I'm going to swap to a fresher motor very soon as it's really lost it's pep on the low-end (something has been "off" since it got rolled) It still runs well but from a stand still it just doesn't pull as hard, with 2 adults in it, got to have a running start at most hills now & it's not an auto clutch issue.
