Poly Torsion Bar Boots

OK, so I am almost done assembling the front end on my Barracuda.

I bought a set of poly torsion bar boots from Energy Suspension, I could not get those things to slide on, no matter how hard I tried.

I just bought a set from Summit made by Prothane Motion Control, and they look very similar to the Energy Suspension ones. I'm afraid I'm going to have the same problem with these.

Has anyone else used these? Any luck getting them on?

And I can't seem to locate some stock rubber ones either.

Any help or input is appreciated, thanks!
I'm looking for a pair of torsion bar boots. LMK if you want to sell your Energy Suspension ones.
