Why don’t my new U joints fit? (Solved, thanks!)

I've either used a vise or c-clamp to install. Never been successful by hand.
Measure inside to make sure yoke hasnt been squeezed too tight??
I’m fortunate to have a press here, so that’s what I’m using. At first I did think that I squeezed the yoke and made it too tight, so I measured both ends and they were 2-1/8” exactly.

Well, the slip yoke is done. Just as easy as that! I was being scared and not pressing the joints tightly enough. Easy peasy. Thanks guys!
