I just did Mine on My 52-3100 the rubber goes on the truck frist than I took a pc. of 1/4 inch wood dowel rod with a flat point like a chisel point and with My wife brushing on dish soap ran it around between the rubber and the glass , than to get the lock bead in I used a crome plated 5/16 box wrench it is the kind You have for ignition parts ,small, put that in sidways and turned it so the rubber was formed over the top of the wrench pushed the lock bead into the wrench ,My wife still brushing the dish soap, pulled the wrench around while I pushed the lock bead into the wrench worked good .
