I'm trying to put my side trim on my 56 customline 2dr sedan.its been 18 yrs ago that my son pulled everything apart.my question is what clips do I need to order? the catalogs dont have too much detail and I would'nt have thought there would have been so many listed. I have got my rear quarters done but my doors and front fenders are a real challenge.front fender has a round hole on  each end and 3 square holes in between,  the doors have a hole each end with two rectangle holes in the middle.  I called concours and was told just order some that look right till I get what I need then send the rest back,but maybe someone has done a customline recently and knows what I need. thanks15
