Dually Fender Attachment

[Trucksareforwork]

Here’s a question for any dually gurus.

I’m going to be converting a regular longbed to a dually. Already have some fenders. The truck is a SRW converted to DRW many years ago, and I acquired it without a bed. It’s a 4x4 gmc 3500.

I do not have the fender to bed side anchors, and as I look around; they appear to be “rare.”

What would you guys say to a mounting procedure that includes a few studs for placement, and then panel bonding cement for fixture?

I realize this would be a permanent solution. Any other risks?

I'd investigate using 5/16 threaded inserts they come in brass,stainless or carbon steel,or time serts. Epoxy the outside before install,then use 5/16th,studs and washers.

I'm not familiar with the factory way of mounting the fender flares, but could you use rivnuts? Would allow you to remove them in the future. This would require some sort of flange on the flare though and I haven't ever looked at one closely to see if there is one.

I certainly would not panel bond them on there. I'd say either through bolt with large washers to spread the load or threaded inserts/large rivenuts/something along those lines and then use some kind of felt or rubber between to isolate them

I really like this idea.

Factory way was a coarse threaded stud that threaded into the bedside. I don’t have a picture handy but they aren’t reproduced that I know of.

I like the insert idea offered above. That would preserve removability and still hold well.

Here’s what one looks like. From the web.
