My version of X-axis leveling rods. I chose to use the mounting bracket of the hotbed for this rather than the Y-axis rods themselves. Simply slide onto each side of the hotbed mounting bracket (the lower bracket, not the hotbed itself), disable steppers, and manually move into place and adjust the Z-axis T-rods until the lower X-axis rod is the same height on each side. You can use a sheet of paper on each side, just like bed leveling, to get them even. Do this before bed leveling.

Feel free to remix if a different height works better for you.
