Needing help with finding clips for body chrome trim!!

Hello and thanks to all of you in advance for help I will receive now and in the future and hope I as well can provide some good advice in situations.

Here's the problem at the moment. The car went in for prepping for paint today, and when the chrome trim came off my car, it's a 67 dart GT convertible, they have little plastic clips underneath, and all I can find are metal or zinc clips and I do not know if they work for the trim if I purchase them. Can anyone tell me where I can find the correct clips so I can have them here by the time he's ready to put it all back together? Any help at all in the right direction is soooo appreciated guys. Thanks in advance, Sean
