I've been at this heavy for more than 15 years now, in all this time I have had several 80' 4/6's, MANY Invaders, just 1 Intruder, and even a couple Interceptors. Other than a handful of parts, I have never owned an 81-82' LTD. It seems that there aren't than many around Michigan (not really sure why?).
I finally found one...It's an 82' and it looks like I will be going to Wisconsin next week to pick it up. It's rough and in pieces, but mostly all there and the price was right.
