Convertible Zip In window

[Mastrcruse]

I have seen many of these on ebay. When did the convertibles come with zip in rear windows? This would be help to change them but I haven't seen/heard of any that actually have it.

Anyone have pics or know anything about it? I am just curious.

Thanks

I have a powered top that came with the zipper, so look for those.
