there is no other difference. however, I would buy the firebird and save you some grief. the metal however looks the same is different in gauge size only slightly and when you cut and weld the patch the warpage is greater than an original and it really is alot harder to work with. believe me the savings will be your downfall. do it right and you will be soo much happier in the long run. It is interesting to note that the roof for a 69 camero will fit the 67 and 68 firebird without any problems. good luck with the project
