Best place to buy complete polyurethane bushing set

[trs900]

I noticed Summit has Energy Suspension sets individually, I would like to get a complete set for sway bar-trackbar-leaf springs, etc if possible or maybe there is no option but to order them seperately. Other brands ok ?
With the wind today and pulling a trailer I was all over the road, 1st thought it might be steering box but there is no play at all in steering wheel the slightest movement turns the tires, this has been happening for awhile just really noticed how bad when pulling a heavy trailer, not a 5th wheel, it felt like I was driving on ice.

Truck was built in Nov 2002 with 6.0 4x4 and only has 51000 miles on it and rubber bushings are shot Florida heat no help, measured front bar and it's 1" diameter.

I bought a couple different sets of urethane bushings from NAPA. They go under the brand of Prothane.

Remeasured front and rear sway bar and it's 1 1/16" diameter which no one lists a part# for, they show a 32mm kit which is over 1 1/4 " diameter. Ford must have used something different on my truck.
