Austin Healey 3000 tonneau fit

[HealeyS3000]

New to the site:

Im redoing a BJ7 and I don't plan on using a top or frame. I've noted the correct tonneau cover has flaps for the top and I was wondering if anyone had ever attached the more sleek 4 seat tonneau to the Bj7/8?  I would prefer that look and do not want the excess boot cover as there will be no top/frame present.  Are the cockpit dimensions close enough to match? Any information would be helpful
