They were very helpful when I got mine. I returned 2or 3 before I got one that was flat to my liking. Guy was a little miffed, but I told him to put a straight edge and see for himself. I have yet to attempt putting it on but its not looking good. Knowing me I will just get the other style too and have both at the ready so there will be no hiccups when I start. I seem to remember something on the install sheet for the apn about having to remove the motor mount brackett to install on some zjs.
