my 91' hatch

Try this - put either a drop of white-out or little peices of poster putty (make sure the putty is small, though) on the highest points of the cams without the cover on and close the hood. If there is a mark either on the bottom of the hood, or they putty is smooshed then you will have clearance problems. At least this way you won't try your clearance with the cams exposed to eat away at your hood.
