Cab plugs on 4th gen 1500 near footstep mounts

[Dusty6914]

Hello all, so I'm wondering if anyone has a idea of where to get rubber/plastic hole plugs for the 3 oval shape holes that are on the underneath of the cab near where the running board mounts bolt to the underneath of the cab. From factory the holes come taped off. I live in the rust belt so I'm looking to see if someone makes some sort of a plug for the holes instead of just tape. I've looked and I can't seem to find anything. Any help or info would be greatly appreciated.

I'd recommend just leaving them open or taping them off. A plug in that hole WILL NOT save you from rust.

You likely know it, but oil it yearly and come summer rinse it out well.
