Formula S (HD) Leaf Springs

Bennoel 10, you are incorrect. I had a 69 Dart Custom with AC. Wheels were 4.5, I believe, and the Torsion were also lighter. The wheels I pitched years ago, but kept the bars in case I were to put together a SB drag car.
Post # 17 if you read it ,I corrected that statement. But your right it's not A/C that got the upgrades, it was a trailer towing option.
