Thanks for all the replies. They pretty much agree with my interpretation. Since I have already done the not exactly pleasant task of removing sound deadening and tar on the Si, regardless of legality I would have to be a sadist to want to do all that again.
roof skins and support structures on civics come out pretty easily with a spot weld drill and some patience. the sunroof under-skin support panel in the Si / ES chassis is *much* larger and heavier than the non-sunroof coupe's single beam support.
I don't disagree with the legality of a full non-sunroof roof and structure swap, or the use of a solid roof chassis under VIN rule, though I can see where the argument is grey at best. I would NEVER EVER call someone out on it though. we did a full roof swap on an Si once. great car, it's now in the ATL area with a new owner.
