I am beginnng to install Moss interior door panels on my '72 B. Two problems--the pre drilled holes don't quite match the holes in the door & the white plastic panel clips (sent w/ panel) are too large for the pre-drilled holes. My plan is to redrill the holes in the proper place and larger but, very carefully so I don't go thru the covering. Any suggestions as to altenate ways to attach the door panel?
