Check your upper air extractors. You may find S7MS numbers in front of your scoop lights. Check your steel frame decklid also. There should be a S7MS number on the lower lip of the decklid. I believe it is on the left lower side, visible with the lid open. My 67 # 235 has these along with functional brake scoops. My other car, 67# 2336, that I drove to high school in 1978, does not have the embossed numbers on the fiberglass and non-functional brake scoops. Hey I ‘m restoring 2 cars also.
