65 Dart front U-Joint rebuild!

Oh MY! Ya, no wonder they changed the design in 66!
Holy moley!
They call it a "Ball & Trunnion" I call it a pain in the ***!

The 65 Dart Bible, says the dust boot can be installed without pressing the pin out, by greasing it up and working it over the pin(which I can actually do) and then work it by hand through the trunnion by hand. Ya right!
I spent 3 hours of cussing last night, without success getting the ruber boot through the trunnion with the driveshaft there. My thumb feels like I got arthritis this morning.

Then I'm looking and measuring and it seems like impossible to get the trunnion far enough back with the rubber boot installed, to press the pin back in, if I go that route of pressing the pin out.

Has anyone ever dealt with this design and what choice cuss words and in what combination worked?
