yeah it is different... thats why i said im trying to figure it out. but im not making any cuts until im 100% positive on what im doing lolthe best way for the 93 civic is to swap roof skins so it will seal correctly. the other option is swap in manual type(flip up).
for you i think you would be better off pull out the metal and go down to a glass shop the can cut to size but you want it to be tempered. the one out of the 91 si, is a differnt type if i remember correctly the crx slides out and on top of the roof where as the civic hatch slides in side the roof skin.
