The original glass is in good shape, just old. Looks like it has yellowed vs. new glass.
It is not intended to be a points truck but have tried to stay as original as possible, with as much of the original parts as possible.
I had to make the same decision on my '38. I decided to keep the original glass, even with all the yellowing. We did have to replace the windshield because it broke when we tried to remove it. I've gotten a ton of positive comments and thumbs up at shows and other events for keeping the original glass. It WILL make your truck stand apart from the others.
