Al - If you have the interior trim package the A-pillar covers fit in that triangular area. If you don't have the interior trim package then I would trim the pieces that were cut out so they fit around the roll bar. I was going to come up with a clip to hold it in place. I wanted to be able to remove the trim piece and be able to remove the dash if needed. However, I never got that far with my build. Not sure if this is what you were asking?
