you'll need either a 9mm or 11/32 socket and/or wrench and phillips screwdriver (a 90deg is even better for the rear). You should have a nut near the front tips of the LH & RH pieces (w/ top down - roll up qtr windows and remove speaker grill and speaker; find nut near the tip pointed towards front seats and remove); one or two screw on down-slope, nut in middle, and two nuts at the end on the elbow ( 4xnuts and 2xscrews per LH/RH piece). The rear piece is removed the same (approx 7 nuts). This is for the upper pieces. The inner molding (LH & RH only) is riveted to the body and IF it needs to be replaced, you'll only need to drill out about 6 or 7 rivets per side (can't remember rivet size). Usually, your lower moldings only need to be cleaned up and not replaced.
Run you finger under the lip of the conv. molding and remove any barrier tape and puddy clumps. You'll find/feel all the nuts doing this. Place a non hardening puddy/resin/epoxy/adhesive...whatever over your hardware and reapply either a very thin weatherstrip or duct tape/barrier tape over it to avoid tearing/snagging your top.
If you replace one, I'd paint all to match or just buy all outer pieces at once. They are fairly cheap.
