That shock tower wrap is for a 1968 and 1/2 Mustang with a big block and maybe a 428 CJ car to my knowledge. I say a big block vice a 428 CJ car as a thought as this was a mid year 68 upgrade to a 1968 Mustang with a big block in it. Who knows what may have happened.
The fact the VIN is for a "C" code car indicates a front end clip as previously stated by sportyworty. That is very curious, but the VIN is what it is so to speak... Fun stuff!!! Who knows what this is!!
