i found a good lund sunvisor at the junkyard today got it for $50 bucks compared to almost $250 new i painted it to match but i am wondering how is the best way to mount it the truck it came off of looked like the screws were just drilled into the sheet metal and gooped up with silicone but that doesnt seem very strong to me so is that how its supposed to be or was that a shortcut job?

thanks 9.ford.5

 

Most of the guys just mount that way, but in my opinion that is not right.
The right way to do it is to use riv nuts. They are like a rivet that has a threaded portion in the center to run a bolt thru. You might be able to find them at auto parts store, some installers of such products in your area might have them. I know Princess auto carries a whole kit, riv nuts and gun in the $30 dollar range.(I have one and it works fine, and they come with alum riv nuts.)
Then you either find bolts with caps or just use alum or stainless bolts.
Just fit first, and then check, and then mark out and drill holes, and seal the riv nuts before crimping on. This will be a two person job to line it up properly. Have fun.

 

yeah i was thinkin about using those we have them a peterbilt its like nut zirk or something i think but by the sounds of it they are the same deal

 

The few of them I've done, the body wasn't flat enough to mount a riv-nut. They were fun enough to try and drill a straight pilot hole.

I did a 99 F150, it was three self tapping screws in to the A piller and then either one or two self sticking pads with a stud that held the middle of the visor to the top of the roof. The screws had a silicone on them from lund, it was a dumb dumb/strip caulk type that shouldn't harden for quite a while. Those three 3/8"ish screws with the heavy threads will hold quite a bit. However they all will flex with speed.

If you didn't get the stud plate, I'd go back for it. It wouldn't be all that hard to recreate a flat plate with a threaded stud sticking up, but it would take some less common tools. Get the old one off the donor truck and pick up some 3m double sided molding tape to stick it to your truck.
