1993 Honda del sol targa top vibrates when on bumpy road?

[I'mInCollegeNow]

When i drive down roads with bumps and stuff my Del Sol's Targa Top vibrates a little like the back of it is bouncing a little. It's locked in and everything. Is everyone's like this or is there something I can do to fix it?

Most likely the rubber seal on the top is a bit old...best thing to do is to have a look around ( try JC Witney) and replace the seal...you may wind up having to get that from Honda directly.
