Targa top CRX

I own a 91 Honda CRX and have been kickin around the idea of doing a targa top. I was wondering what would be the best way to support the body to prevent it from bending after I cut the top out? Also would I have to brace the windshield?

if its on bags lay it out then weld maybe a straight bar and 3 diagnol? make it straght 4 sho cuz ill tell u it will be noticable
