Track Bar Hiem Joint size

[88XJScott]

I'm looking at building a track bar for my 88 XJ. Just swapped in Waggy 44's and custom long-arms,
but the Rustys track bar just aint cuttin it with bushings at both ends.

I will be running hiems at both ends cause I'm not worried about the ride. What size would you guys recommend?
I plan on running 1.25x3/16" wall DOM for the bar itself.
