Ah. Well thanks for the info on the Blazer channel curvature. That was my concern - that I might end up buying something that did not fit at all. Yes the felt is the least of my worries. I found several suppliers of flexible felt channels that fit inside the metal run channels. Now if I can just find some channels not as badly rusted as mine. If I find some I am seriously considering electroplating them in copper or some other corrosion resistant metal, then several layers of epoxy paint.
