Torsion bar seals?

First, I also had a SUPER easy method. First lube up a 1 1/4 socket, get a small piece of plastic to protect the end of the boot and make a vise sandwich

vise jaw - plastic - boot - socket(in large end) - vise jaw

Squeeze vise until the socket is in the hole, once in there, push that sucker onto the torsion bar, i was amazed at how easy this was to do. Another method was to force a smaller socket in first to start the stretch, and then push in the larger one after.

Have a question though, i got the polys on super easy, but now i cant get them to go over the torsion bar mounting point, any tips on making that work? Also, since the polys have no metal support inside, what holds them onto that spot?
