Hi, I see a lot of other car parts end up fitting on a 1975 buick riviera. I am looking for an Original full front bumper filler for a 1975 buick riviera, and a Original rear bumper filler long center bumper filler piece for the 1975 buick riviera. Maybe the 1974 and 1976 buick riviera front and rear bumper fillers will work for the 1975, since wikipedia says those years are the same generation. I am also hoping that other models of cars like the buick electra parts, and other models of cars ,have parts that interchange with each other,and will also fit a 1975 buick riviera. If so, this would make it a lot easier to get front and rear bumper fillers from certain models of cars, that will fit ,and work for the 1975 buick riviera. Or if you have the Original 1975 buick riviera front and rear bumper fillers ,I would just take them, if they were in good shape.If anyone has the original 1975 buick Riviera front and rear bumper fillers, or ones from another make of car that interchange perfectly,So they just bolt on like the original 1975 buick Riviera. Please take some pictures, and then we can work out a price for them. Thanks Carey
