to take it out use a razor knife , and cut the rubber away from the pinch weld until you can push the glass out.
some shops find the trim difficult to install, but all they need to do is put the trim in the rubber, and then put the rubber on the w/s, and then install.... really shouldn't take them 5 more hours.....
corts 60 did a real good write up on installing his w/s with trim at home , I will try to find the link for you , and maybe you can show it to the shop , so they know how to go about the process....

all modern shops do anymore is glue stuff in, so I suggest trying to find an old shop, and hopefully one with some old employees in their 60's that know what they are doing, and how to deal with the old vehicles that have rubber gaskets.
