Had a buddy pickup tow mirrors for my 2015 F150 but one side is missing the weather boot. Is there a source to purchase a replacement?

 

If you're talking about the seal between the base and the truck, junk yard.

 

yes that’s what I need. No junk yard near me. Will need to try carpart.

 

Is it flat like a gasket? Maybe you could make your own. Make an outline of the other side's seal on wax paper, edge it with narrow painters tape, lay a thin layer of black rtv and peel the tape.

That is if it's flat.

 

Use the seal from your original mirror swap out, they are direct fit

 

great! Thank you.
