Side Trim Removal

I have a 1967 Dart 270 with the side trim / spear that travels the length of the car up almost on the body line at the top of the fenders, doors and quarters. ( Sorry, I don't have the tools nor the know-how to post pictures.) The trim is in really good shape with no dents or dings, just needs a good cleaning and polishing. I want to CAREFULLY remove it without damaging it so I can prep the body for primer. Can anyone tell me precisely how to go about it or direct me to a shop manual, etc. that can walk me thru it? Thanks in advance. If I can remove the trim without hurting it I will probabaly put it up for sale. Going for the SS/AA look, dontchaknow.
