It been quite a while since I have been on the site, so sorry for the long delay in responding to your question.
I had to bend the loop portion of the French lock outward to clear the smog tube fittings. It will not fit over the top side of the tube.
I just now quickly looked thru my pic library for a pic of an unrestored 69 Camaro (manual shift car) that still had the exhaust manifolds and French looks but did not see one. If I can find the pic, I'll post it.
