How do you remove plastic window rivet?

Gave it a good soaking( had previously sprayed it at initial disassembly). Laid out on bench, used small punch, rubber mallet and small 1/2" socket 1/4 drive. Trying to be super careful as those vertical plastic leading edge pieces appear to be intact and good shape. Couple firm but gentle taps and it popped right out!
I may even be able.to reuse them.
Thanks @Murray !:thumbsup:
