Custom Cruiser lower "moldings"

Any Ideas on removing the lower body moldings {panels} ? I want to fix some rust that is starting under these. I know there are some type of clips, but knowing how hard these are to find, I want to prevent from breaking anything. Thanks!

The panels are held on by screws/bolts along the bottom edge depending on which panel you are referring to. The doors have metal supports along the bottom and are held to the doors with 11mm castle nuts. The door panels are held to the supports with fasteners (impossible to get, but I found some that can be modified to work). The upper edge has small pins that fit into nylon inserts in the body panel. If you use a panel tool (looks like a bent split tip screwdriver) and put something under it to protect the paint, you should be able to pry the pins out. The rear quarters have two, close together, at the rear corner. If you break one or more, you can soften the heat "sealed" tabs along the top edge, and reform them to get the metal strip off. After replacing the pin, heat them with a soldering iron to reseal the strip (I used a heat gun, but ruined a panel figuring out how much heat to use). The pins are hard to find, so be careful with them. Roadmaster front top trim has similar pins, and the nylon inserts. The pins and inserts can also be found on the bottom trim on the doors of Caprices. The inserts are almost impossible to get out. I have a few of the pins stashed, but no inserts (thanks for reminding me, I am headed to the JY tomorrow, and will try to pick some up). If it is a 91, and you have some issues getting it back together, PM me, and I may be able to help. The 91s are wierd. 92s are pretty straight forward.
