It's amazing you still have it at all. The stuff was falling off half of them by '98. As far as I know it can't be had, though there may be something out there aftermarket that's similar. I had some luck with 3M tape(if you still have all your pieces) but it doesn't seem to hold as well on the aluminum trim as it does sticking rubber to a painted surface on other cars.
I admit these were lot cars and I never cared enough to take the time to rough up the surface before I put the pieces back, just cleaned it and taped it. A scratchpad might help adhesion.
