You're right, I'm wrong. I was referencing the usual change from a C4/8 inch to a C6/9 inch which does get into triple digits.
Depending on a number of factors, the weight difference can be 25-35 pounds. Not insignificant for unsprung weight in a ~2300 pound car.
Addendum: This page says 45, which is closer to my experience, and also makes a good case for the 8-inch.
When I selected components for my Mustang, I had a free hand and an open checkbook - and after a lot of careful investigation, decided against both a C6 and a 9-inch. I am using components (roller/teflon C4, Randy's 8-inch Traction-Lok) identical to several local racers who have had everything fail but their drivelines.
Unless you're running a true monster-motor (600HP+) and are going to be putting a lot of quarter-mile time on your Cobra, I'd argue strongly for a well-set-up 8-inch; plenty strong enough and at least 25 pounds lighter where it counts. (Actually, I'd argue that a solid rear axle has no place in a short-wheelbase performance car, but let's not go there...
