ATE caliper rebuild seal problem

[turbobenz]

I cant get the dust boot seal to fit over the caliper. Its just not big enough and doesn't stretch because it has a metal ring in it. Ive tried c-clamps and everything, it just wont seat. Has anyone ever done this? Whats the procedure? And which way does the metal retaining thing go back in? I figuered it went in only a certain way, but I was wrong. My crappy FAG rebuild kits (yes, FAG is a brand) don't have instructions either. Please help, I have three more of these to do and my blood is already boiling.
