Also -thanks for the link to the removal of the pin, but is there any other way to get the pin out without taking out the screws.

Not really. I suppose you could just needlenose-rip the thing out, but that seems a lot more destructive than unscrewing the mount.
It really is a simple job as long as you're careful about it. I bought a handful of old Sears lenses online that came with the pins - I went to Walmart and spent about $15 on a screwdriver set and a magnetic dish to put the screws in and managed to do all three in maybe a half hour - and that was with distractions added in.
