1968 barracuda header panel and emblem for 1967 one

hmmm aren't they the same panel ? the 69 has the bump to match the hood ridge but 67 and 68 hoods are both flat along the front edge .
The difference is the 67 has Plymouth in individual single letters across the face. The 68 has Plymouth script on the left side more on one end. Otherwise as far as fit etc. I believe you are correct - they are the same.

Best regards,

Bryan
