Not sure if this is the right place to post this info. If it's wrong please let me know and will move it. I have a 67 Acadian Canso s/d, and just so you know, if your replacing fenders. But the fenders on the 66 and 67's are the 66 fenders. That is how they came out from the factory. Many guys don't believe this info, or are just surprised. I did some checking and also talked to two Acadian Gurus in B.C. and they also confirmed this. They both fit, but you would have to change the grill, bezels etc. And oh yea.... i found out the hard way...lol. Thank you.
