I have a 1973 Cougar XR7 convertible that I'm putting back together after 40 years. It is a Q code, 4 speed, with a 351 CJ. Everything is coming together pretty good but there is a part that I cant find any history on and I didn't label it when disassembling the car. Wondering what it is and where it mounts. I can't seem to find one to look at, so if anyone could give guidance I would appreciate it. Thanks in advance. Gordy.
