Chances of that are slim to none, your best off placing the mlds on the car fitting them where they contour and fit the body best, tape them in place in a few spots to hold them on the vehicle, use some 1/8" or 1/4" masking tape/pinstripe tape/etc, tape a line directly to the edge of each side of the mldg butting up to the mldg, then remove the molding, the tape lines are now your template, measure between the 2 lines to find CENTER for your attachment screw, and space out your clips accordingly and as needed to retain the mldg to the vehicle, just don't overdo it with clips, keep in mind some mldgs also use a threaded stud or barb clip end retained inside the mldg that is tightened inside the vehicle, some just use clips, they all vary... when installing the clips, seal the screws with body CAULK, no silicone that eventually promotes rust, personally I'd only use stainless steel screws...I've done this many times in the past, esp on finish paint vehicles that received a top later on down the road

FYI, some mldgs are rather low in profile, make sure the screws or rivets, even nail heads are lower than the installed clip, otherwise you'll end up with dings in the mldgs when you snap them on
