I am replacing the door glass in my 56 tbird. I have the glass out of the door but I am finding it difficult to remove the glass from the bottom channel. The chrome upper molding came off the glass without a lot of trouble. But the bottom is a real problem. I have looked at the shop manual and there is no mention of how to remove the glass. I have tried to heat the channel with a heat gun but did not help much. Any Suggestions???????
