Hi - I'm hoping someone out there can help me with this. I have a 60 Electra 225 convertible project car. Over the weekend my husband & I decoded the VIN tag and found it to be an original bucket seat car...but the seats are long gone, replaced with a bench before my husband bought the car (back in '85). I'm told that any full-size GM bucket seats from 1959 to 61 will fit. Is this true? how about later years? Thanks, Jodi
