Bed Rack on Rails?

I know the 2002 Thule Tracrac TracOne will fit my 2002 extra cab 3.4L prerunner. But has anyone finagled the track mounted Tracrac SR? Straight out from Thule they say it doesnt fit the 1st gen, but I know y'all are craftier than that.

 

I don't know if this will help as I'm not sure about the Thule but if you're looking for options, I ran a Front Runner bed rack on mine for a while. The rails mount on the inside but I believe they have a top mount these days as well, which would be handy if you also want to run a tonneau with it for example. (You'd have to look but I'm pretty they have one, even if its for a different midsize, you can make it work.)

 

Thank you so much! I am going back and forth between a tonneau and keeping my dad's crossover box.
