I've been looking around for runners for the side sliding glass in the top. (Some have full glass and some have sliding glass with deflectors, like mine). The runners are shot in mine and leak when I hit it with the power washer. Chevy doesn't sell the runners but they will sell me a complete window assembly for $425 per side. Classic Chevrolet here in OKC can't find them at all. Any one have any idea where to find them?? Thanks.
