I just finished installing the inner piece on the right side last night. What a PITA! There is so much wrong with the piece, it might have been easier to build one from scratch. All the curves are wrong and the base is not tall enough to reach the kick panel. I had to slice and dice it, recurve it, etc. Luckily, I left the outer cowl in place until after the lower hinge pillar, inner to outer cowl filler, and kick panel were replaced. Then, I cut and replaced the lower out cowl. This way, I maintained alignments and curves properly.
