Once it was in the garage I finished up plug welding the driver's side frame and threw on primer to hold me over.
I worked with Hellwig (phenomenal customer service) to source a rear sway bar for the truck and found that their Big Wig F350 bar would be the perfect fit. The Big Wig bars are 1-5/16” diameter, solid heat treated 4140 chromoly steel that are aligned to the heavier duty applications. I ordered it on Amazon and it arrived two days later.
