    Why did GM offer both single and double wall tops. Was a double only available with a CST option[as maybe better insulation]? Did you have a choice? I would assume that the single would have to be thicker[but maybe more prone to cracks due to lack of flexibility]? Just curious.
    I also understand that all tops were options and base models came with no top or door glass. Wonder how many of those were sold?

    I don't know why they made two different types, but the double walls sag in the middle of the roof and suck to remove if you have interior panels in the rear. I've seen both types on every year model ( don't know if that's how they were originally) But single wall is the way to go.
    Perhaps they contracted different suppliers.
