I have a rockymounts ‘driveshaft track’ (looks similar to the one you ordered), as well as a rockymounts hotrod in the rails on my 2012 Tacoma, and I find myself almost always using the hotrod-it is rock solid and holds the thru axle securely while fork tends to bounce and rattle with the driveshaft. It was also a little easier to install without removing the bed rail
There was a tacoma world post on the hotrod that I can’t find anymore, but this is the mounting hardware I ordered from amazon. Not sure if the rails have changed between tacoma models
3/8-16 x 1" stainless Socket Head Cap Bolts + lock washers (drilled out the holes in the mount slightly to fit)
