Here's what Energy Suspension says about their dust boots

I bought P-S-T's 1.03" tbars and there premium seals.
I couldn't get them on no matter what I tried.
A friend and his Big wife came by to see car.
I told them the problem I was having, she said let me try.
The seal was put on shop floor large side up, tbar hex was put into place.
She then took a board I had around and put board against her chest and put her weight on it and the damn thing went right on !!
Did the second one also!

True story!
That should be in the instructions
