I want to upgrade the sways on my NY. I have a 1 1/8" and a 1 1/4" front bar so thats covered. For the rear I have a 87 shelby z axle. But ive also read about clamping a piece of 2" flat stock to the rear axle to stiffen it up. Whats the prefered option? Im a fabricator so using the flat stock would be easier for me. Id also have to swap my drums to the shelby axle to keep my e brake.
