My experience in the past with different truck sway bars has been beefing up the front where the majority of the weight is makes a world of difference. Not a lot of weight in the rear that gets slung around, unless you haul alot of cargo.
On one truck I replaced the stock .75" front to a 1.125" and installed a .75" rear that had none before. Looking to rally race it. It rode horribly. Removed the the rear and it drives 140% better than before the front swap out.
Pretty much most of the modern sway bars have little sway links on the sway bars in the rear, so adapting any sway bar on an older truck is going to be trial and error.
I will find out this summer when I get my '51 3100 with C4 Flat Out Engeneering suspension with an upgraded larger C5 front bar how it handles on the road. I might be adding a rear bar.
