Hi, I'm working with a manufacturer of reproduction filler panels and they are making the following sets now. I have a couple of compatibility questions shown below. Please let me know as soon as possible. Thank you!

- 1974 & 1975 Cutlass two door full front and rear. Are these the same as the 1976-1977 Cutlass four door rear?

- 1980-1984 Cutlass four door and salon full front and rear. Are they the same (four door and salon)?

Thanks!
John
