I had always thought that the height of the legs were different. Or am I thinking of a 71 Mustang spoiler? One of those Mustangs used a shorter leg, about half the height of a Cougar leg.1970 Spoilers for a Mustang and Cougar are EXACTLY THE SAME...on top of the decklid.
On the underside, the reinforcement pieces ARE different.
I believe that the reinforcement pieces for a Mustang have been reproduced, but I don't believe that the Cougar ones have been.....yet, unless Don has them hidden away!
Or if he wants to be noticed, he can buy this on from Don: www.cougarpartscatalog.com/rnspoiler.html . LOL J/K.well if you were a rich white boy then by the correct wing , if your a poor one like me by the repo from don for 117 like i just did and very few will notice as you go by at 70 mph.
SlowMerc: Check the sig -- I've been in them for quite a while ('83) and owned an Eliminator during that time. I do focus on 70 only and might get my facts for a 69 incorrect once in a while. I think you jumped off way too soon and did not read my original post where I warned him that the spoilers are not interchangable which is a fact. The spoiler includes the mounts. Now you slap me upside the head and tell me to get my facts correct. You simply interpreted my response to be "wrong" since you know everything.dfw.....
I was making spoilers & hood scoops before DFWcats was a thought in someone's mind.....
But obviously, you have not been around 70 Cougars and Mustangs all that long, otherwise you would have known about their interchangeability, and their minor differences in mounting hardware.
