I took a road trip last night after work and scored a nos pair of Direct Connection Big Block Torsion bars. I bought them from a guy who purchased over 20 years ago for his project and never used them. They still have the zinc dicromate finish on them and will be a great addition to my Duster build. I haven't mic'd them yet.. He stated they measured 1" in diameter. Made in Canada!! Much better than the offshore bars that are out there now.
