I wonder if they (or someone else) will offer Blazer topper glass. Thankfully mine is good, but I've noticed the glass seems to be in relatively high demand.
Side story:
When I sold the first topper I had for my Blazer after finding a nicer one, I had numerous people ask to buy just the glass. One guy finally agreed to buy the whole thing (after asking for just the glass and me saying I wanted to sell together), and when he showed up to get it, I realized his plan was just to remove the glass, sawzall up the topper into small pieces, and throw them away somewhere else. I told him to just take the glass because I didn't want the topper to totally go to waste. It was kinda cool, several weeks later someone wanted the top without the glass because he was going to cut some of the non-essential fiberglass away and make it into a sort of hard safari top for his 2wd Blazer. So I was glad we didn't throw the top away completely.
Anyways, seems like there's a market for the Blazer glass too.
