trim for vinyl top

Could you be a little more specific about which pieces and what type of car? It's hard to answer your question with the info provided.

Its a 74 swinger 2 dr. with vinyl top trimmed in chrome all around, found self bending/distorting the trim/ holddown pieces trying to get them off with a screwdriver, etc. is theree a trick to removing it? I noticed there are plastic clips with small metal studs all the way around, would like to re use the chrome. Thanks, GARY
