No, the top "bar" that goes around a truck door that holds the glass channel and felt will interfere with the factory hard top. In other words, the hard top and the window channel will try to occupy the same space and the door won't even come close to closing/latching. You could take the top off and it would probably close just fine, but that would defeat the purpose of "getting through he winter".

On the other hand, from the factory blazer doors were simply truck doors that had been cut. The factory removed the window channel and bolted them onto blazers. People continue to do this when rebuilding blazers because a nice truck door is way easier to find than a nice original blazer door. LOTS of threads around here discussing the topic in great detail.

Sounds like cutting your nice 68 doors down isn't an option either, you give the impression that they are dedicated to another project.
