Sedan Sail Panel Removal

The sail panels on my CHP car were bad and probably came out in pieces and I do not recall what held them in.
I know there were clips bonded to the back side but do not recall where and how many along with the proper direction to move the panel to remove them.
I have another car with perfect panels and do not want to harm them removing them.

If it matters it is a 1969 Dodge Polara 4-door sedan.

Thanks,
