The floor pan of my 72 cutlass convertible is rusted through and will need to be replaced. I'd like it to be original and not repop since I understand they do not make an exact version trunk pan replacement for a cutlass (works dimensionally but is not a Cutlass pan)

So my questions are:

1) Are there any differences between the trunk floor pan in a convertible vs hardtop cutlass?
2) Can I only use a trunk pan from a 70-72 body or will a trunk floor pan from earlier body types match the one used in a 72?
3) Anyone have a nice rust free trunk floor pan available for sale? If yes how much, and would you be able to bring it to Homecoming this year?

Thanks.

Steve
