I don't have them, but have seen enough of them to have a theory.
I would think all that you would have to do is remove the from bumper, and all your bolts would be exposed. From there it is simple, get an air gun and the proper size extension along with your ratched head. I've seen pics of these fenders when they where installed on another cougar, and it looked pretty easy. I think all in all there are about 6-10 bolts that have to be removed. Then it is a matter of installing your Z-3's and putting the bimper back on. Again this is in theory, but it is based on the info I've collected on this subject. Good luck.
