I'm in just about the same boat. but what I'm gonna attempt ive seen done.. all you need are 2 of the thin medium length pry-bars, cover them in duct-tape so they don't clip any thing. go around and hammer bead off with the pry-bar. then used the covered pry bars to work the bead over the lip section by section. use grease. its the same way its done in the shops with those fancy machines but less the technology..
