3rd Gen Top On A 2nd Gen?

I've seen lots of threads about "will a 2nd gen camper fit a 3rd Gen" but not the other way around. Supposedly the 3rd gen has a 1" taller bed so a 2nd gen top will stick up 1" higher than the cab. That means it'd be 1" shorter on a 2nd gen & I'm okay with that. There's more 3rd gen tops available around here than 2nd gen is why I'm asking (been looking since Feb. but I have a SofTopper so not in a bind @ the moment). The question is the rear window fitment. Does anybody have any pic's of a 3rd gen topper on a 2nd gen? Thanks.

 

The bed dimensions aren't the only difference too its the way the roof line curves and also the tailgate shape. 3rd gen tailgate is thicker (looking at it) than the second gen which is kind of flat. Also from what I hear the railings are also at different heights in comparison to the 2nd to 3rd gen.
