I removed my windsheild frame today from the '42 and its in really good shape except for a little hole in the lower pass side corner. The center bar came out easy, the v-bars are being very stubborn. I was able to remove the old glass by cutting the rubber and carefully spreading the frames apart. The tech-tips said to cut a 1/4 ect, but i can't go that route. How can I get these v-bars out without cutting or damageing the frame? Heating?
