Here's the definitive answer:

But I can tell you it seem to take considerable force to press the shafts down. It bent my homebrew apparatus.

The washer & clip arrangement doesn't load me with confidence, that's for sure. But getting those clips in place seems to distort them and as obnoxious as that washer is I think it's necessary. I can't think of what might be in the way when you try to compress the springs. You might want to do a trial run with a light film of grease on the coils. If they totally bottom against each other the grease will show it.

There is no risk of blowing out the clips in the differectial by pulling the shaft against the flange? Last thing i wanna so is tear down the trans again! I was using a 1/4" plate and that thing was bending like a bannana! (not the one in the pic. I made another one)

If I understand your question right, there is no risk. The flange is being levered down upon the shaft itself so that won't load the clips in the differential. The springs aren't pressing directly on the differential carrier or the case, they're pressing on those conical washers. At that point I thought the load was splitting between the differential carrier and the stub shafts.
