Does anyone know if the window felt runners (inner and outer) found at the top of the door on a 79 Cutlass are the same as either an El Camino, Malibu, or Monte Carlo? Original Parts Group out of Seal Beach, CA, has some exact reproduction felt strips with the stainless steel beading, but they are listed for an 81-82 El Camino and Monte Carlo. The outside felt runner is 48 and 3/4" long on the Cutlass. I sure would appreciate any help on this, because I have hunted long and hard for some quality replacements! Thanks in advance for any assistance!! Best, Bob
