how do I remove the 2pc trim on the inside of the A pillar is it a snap fit only ?
The small center trim piece is held in by three clips; one at each end and one in the center. You can pry that off. Once that is removed, you will see that the larger main trim piece is held on by two pop rivets. Those would need to be drilled out to remove the larger main trim piece.
Did you have much trouble getting the rivets out? How did you do the lower one which has so little clearance from the instrument binnacle?
Not at all drill out the head the rest stays in Put a 2 sided sticky tape on a bend metal Slide it true the a pillar holes the are very close to the rivets push the rivet true and on to the Tape and take it out this is why self taping screws are better for the next time
