Those look like 68s. 67s have two clips for the temp sender on the intake side. 68s don't have any clips and 69s have one clip on the exaust side. Right side is the same on 67 68 69 except with ca. smog. The bump on the end is correct for first gen. and the spark plug stand in front of the bolton the left side is also correct on camaros. I don't know anything about 70s
