Ok, so adding up everyone's comments, this is what I am coming up with.. First off, I do not see any thrust block or pin in the exploded view in the TSM for the twin grip, only for the std rear end, But I do see what you mean by them in the two photos. Also, I think your last comment is correct. I think the two sets of splines are not aligned. I think that is what the TSM is referring to on the twin grip when they say do not pull one axle out and move the other or they won't go back in. You say the parts could have wear resulting in this, but the TSM seems to indicate it will happen with new parts.

So, can I get through the tube with a long drift and line the splines up, or do I remove it all from the carrier and have to line them up? And, do the two blocks, as you call them in the last photo need to be removed regardless? It looks like they tap together and are held together with that center roll pin? I'm figuring that is what Ross was referring to in the first reply. I did not see any pieces in the drain bucket, but I will look again to be sure. I still have it on the floor.

Thanks guys very much!

To align the splines for axle install, push them both as far as they will go then have a helper hold a pry bar against 2 lug studs while You do the same on the other axle and You turn a Your axle a little then see if it goes in fully. You may have to do it a few times but sooner or later it will seat. Repeat on other side. That last bit is the axle splines hitting clutch plates. They wont turn when You rotate the axle but the spider gears will eventually they will line up. You won't have to turn but maybe 1/8"

There will be more......especially if you buy a 70 amx

Actually, I have only done the left side, the pass side is still together. I was just going to go one side at a time, I haven't made it to the other side yet!

The inner seal is new, but it is in correctly. When I try to install the axle and push, it is definitely a heavy thud as I try to get in in. It is not a seal problem, you can hear and feel it coming from in the center section. It is shy about 1/2 inch or more from going in.
