interior upholstery

Any suggestions for seat upholstery and door panels or material for a '67 cuda convertible. Doing a resto and having trouble finding replacements for the 'a' body. Particularly the rear side trim panels.
Thanks
I looked at my classic industries catalog and it showed rear panels for the 1967 - 1969 A body convertible but it doesn't say anything about a particular body style. I hope this helps.
