Looking for where I might be able to find a retainer clip for my 88 Convertible. It’s blue and goes in the cover piece for the hinge cover on the convertible top.

You can try these guys, they might have a suitable sub: https://www.clipsandfasteners.com/
The shop manual has the part numbers in them. I was just lubricating my vert pivot points this morning. I wanna say the part # is FB67-68-29XA, but don't quote me on that.
Speaking of lubing pivot points, how does you vert sound when you lower the top? Mine sounds better, but I think I have some groaning coming from the top bar (roll bar?) linkage. And I am not about t begin dismantling the headliner, etc.
Anyway, good luck with that piece,
