I was looking @ the www.FranBishopRacing.com website and saw "Convertible Door Alignment Wedges" listed (w/ no pic of course), and was wondering, WTF are they? It's probably something stupid but I've just never noticed them before on my car. Do I need some of these to align my doors better so they they don't look slightly open @ the top?
