NAPA Has an O-ring kit with a very small dia. o-ring material. If I remember correctly you can get in several different diameters. You cut off what you need, any length, and make your own O-rings. I think it would work well for a gasket replacement if you have your dash all apart like I do. I got one of these a few years back when I took mine all apart for painting. Can't lay hands on it right now to give more details.
