I'm getting near the point where I'll be reinstalling the drip rail molding, and if I recall correctly there was (and the body assy manual indicates that there should be) a rubberized seal/gasket between 517A10 and the body. Something along the lines of 0.88" wide by 1/8" thick. I don't see one at my go-to NPD. The MPC picture attached does not show it.
Am I right about this, and if so does anyone know of a source?
