Hey, pump looks great. I was wondering if you could tell me how you got the glass into the rubber. I am currently restoring one just like it. My glass came out of the pump and had what I believe to be original molding. It is the R105 rubber. My biggest problem seems to be that the glass is slightly too big and has square corners, however the opening has round corners which also gives the molding round corners when placed around the opening. Any help would be greatly appreciated.
