I do have the twin stick. As far as I know, birfields and diff should be good. I'm not sure about the Aisin hubs. I've never really had a problem with them, and I'm not sure how I would be able to tell. I can turn the driveshaft with my hands when it's in 2wd with the hubs free, and then if I lock the hubs I can no longer turn the driveshaft. The problem was that there was no power going to the front when I was actually in 4 and driving. If I was home right now, I would have no issue just bombing down to Redline, but I have to keep it convenient for the people I'm running around. I'll see if my brother is willing. I'm sure he wouldn't mind checking out the shop too.
