I recently purchased some A-pillars to paint body color. They didn't come with the "tracks" on the backside, does anyone know the part number for those? Also, I have access to a pop rivet gun, is that the way to go about reinstalling the tracks or just using bolts as I have seen on here somewhere before?

Also, if anyone has a write-up (with pics would be nice) for removing/installing the exterior A-pillar, I'd appreciate it.
