3 piece moulding removal and installation question

[80stepsideguy]

Got a question,
my cab has a 3 piece moulding set that wraps around the back.How do i remove the clips and reinstall them?1 of the corner mouldings is gone and the other is trashed but i got a good pair to replace and like to reinstall them after it gets painted(eventually).I looked inside and cannot see any access holes to get at them.Also does anyone know any trim refinisher?I got 2 of the rear center mouldings 1 that was damaged in shipping and 1 thats in good shape but has some blemishes here n there and like to get a price on them both.

thanks
pat

you should be able to reach them from the holes in the rear cab corners.

Reach up inbetween the inner and outer cab corner behind you seat 5/16 I think.
