Hello american friend. I am Italian and I joined this forum because I own a 1972 buick riviera base, and I have the same problem that I understand you had in 2019. I have the same interior but one front bench, (not two seats) of black color. I bought the pro fit cover in Alabama and they sent me the wrong thing, even though I sent them the photos of the car .... absurd all this! Now I ask you can you tell me where I can find the front cover for my Riviera?
thank you very much
your italian friend Alessandro
