Alpha?? Heavy?? Not really!! Try yanking a Bravo off by yourself a few times!!! I can do it alone, but REALLY prefer a second set of hands to do it.
At least you have the gimbal bearing covered. Sorry about the misinformation....I was under the impression they had to come out from the inside....not the outer side of the housing. Good to know!!!!
As for the top nuts on your mounts, you might just give it the ole undereducated try.....lube em up with some antisieze and see what happens. Taking the stringer bolts out would be the last thing I would want to do.....much harder to align when putting it back in. The mounts aren't that expensive either......might consider just getting new ones.
