I picked up a used 2 piece fiberglass tonneau for my 95 mustang. It did not come with any type of mounting hardware, and the guy I got it from had never installed it on his car, so he could not help with this question. For the guys that have these on your car, how do they attach? The back has tabs that slip into the rear cowl, just like your factory tonneau does, so that is straight forward, but what holds them down in the front? This one has a push post on each cover, but there is no place for it to push into a factory hole. There must be an additional mounting bracket with a grommet for these to pop into. There are no markings, or brand name on the covers, so I can't go back to the manufacterer. So if anyone has a set up like this, please forward the manufacterer info so I can purchase a mounting kit. Thanks much.
