I had placed a call to a friend in California that had replacement quarter glass made for his 1959 Eureka, and he told me that it cost about $475 about 8 years ago for one piece. Until Atti posted the Herculite markings on the glass, I just assumed that it was safety glass. Now I realize that it is tempered, just like the rear door glass. I suggest that you purchase all 3 pieces if your budget will allow. Paul
