would they fit? I'm trying to get an idea of whether or not the roof is similar in these points, if so I'd like to get a brat roof with t-tops, and graft it into the hatch roof

Chef tim already did the brat tops on a hatchback

 

The doors will swap over, the windshield should too, the side window glass in the doors IS different (my brat has hatch doors on it)

i do know that a hatch windshield is different than that of a wagon, brat and hatch door glass is also different.

 

but i have seen chef tim's hatch, he cut out the roof section between for the fun tops, neato pimpin'

The Fun Tops are cool in the Hatch, but I'd suggest you find a very competent body man to do the job if your not experienced with that type of work. The guy I finely ended up using is from Belarus, he said it took more time to think about how to do it then the actual job.

In my country, we have saying. Measure one hundred times, cut once.

When I told him we have a simular say but we only measure twice he seemed very impressed....LOL. I also wouldn't recommend this on a Hatch that is in really good shape, or something you will drive every day as it will probably leak at least a little bit in the rain/mud. Other then that check out my gallary for some photos. later and good luck with it. Tim
