Hello! I have a 1978 Buick Riviera LXXV (75th Anniversary) car. I am currently restoring it. Does anyone know where I can find these NOS parts and at the best prices? This what I am looking for: Tiffany extra plush gray carpet set (NOS or good match), NOS 1978 Riviera black front floor mats with Riviera logo, NOS power antennae, NOS quartz clock or somewhere I can get mine fixed, NOS interior stainless trim, NOS outside rear side fixed window stainless trim (between window and vinyl top). I am missing the stainless trim above the armrest on the passenger side in the back seat area below the fixed side window. Just curious if anyone has good sources for these parts. Thanks!
