Bed Rail Threaded Nuts for Securing Canopy

I'm looking for these threaded nuts that slide into the bed rail with threaded vertical holes to secure a canopy. Like these:


When searching, I can only find the ones with horizontal holes for attaching tie-downs and such. Like this:


Anyone have a link where I can purchase the ones shown in the first picture with vertical 3/8-16 holes? Don't want to use clamps.

If it matters...2007 Tacoma base model and Leer cap. Thanks.

Not sure if these are right, but I would think any leer dealer could get some
