Need help with locating an underbody insert plug part or bolt to seal side step mounting holes?

Sorry for the silly question, but I sold my OEM side step bars and forgot to measure the mounting bolts. Now the holes are exposed. I
looked at another Tacoma on the street and saw there was some plastic inserts with a groove for a flat head screwdriver in place. I have contacted three dealer parts departments and none of them can seem to locate a part number. Before I go buy a bunch of guess work screw-in inserts or push in plugs can anyone help send some light on a part number or share an example of what they are using to fill these holes. I want to keep the moisture/dirt out. Thanks for helping.

 

I'm about to remove some side steps too, I'd also like to know.

 

I've bought various size plugs at Lowes in the hardware isle. They have lots of drawers full of small hardware items nobody sees unless you pull the drawer out. Good luck.

 

thanks sig45, i'll give these a try.

 

Thread pitch is M8x1.25. I just bought the bolts for mine about a month ago

 

TB, So you used metal bolts vs plastic inserts? Thanks for contributing the info!

 

Wrap the bolts with a little Teflon tape to keep out moisture/rust.

 

Good tip! I'll ordered some the plastic inserts for $10. But now I'm thinking the bolt Teflon method is a much better solution. Thanks again! You da man!

 

Yep, I just bought grade 8 bolts and put a little bit of anti seize on them

 

Thanks again fellas, got the bolt holes all sealed up!

 

thanks! sold the silly running board/steps from my 18 pro and wanted to fill the holes as well. dealer wanted $34 for the plastic plugs

 

Will These work on a 3rd gen too? Removed my Predator side steps on mine and wanna put something back in the holes.

 

I don't know.

 

That’s why when I sold my side-steps I kept the bolts.
