I did have to remove the thrust bushings from the sure grip center when I installed these axles. I thought the open diffs were set up differently, but I'll check it out again (I never looked too close as I've only ever removed them...). I might just grind the axles down like mikedevore mentioned. I just wanted to make sure I wasn't missing something stupid first (it was midnight when I was working on it, after all).
I'm somewhat familiar with the green vs. tapered bearing situation, but definitely still learning. I've always run tapered, but was in a bind and I got these axles with green bearings on them cheap second hand. So I'm running them for now.
