8 1/4 Sure Grip

Looking for a 8 1/4 Sure Grip for a 74 Dart Swinger. The one currently is a 8 1/4 with 2.73's and a one wheel burner. The 383 needs a posi and something around that 3.23 or 3.55 range.
I heard that the Dakota's run the 8 1/4's.

• Did any of them come with Sure Grips?
• Any with mid range gearing?

Could one be so lucky as to be able to take a 8 1/4 Sure Grip with 3.55 gears right from a Dakota and saddle it up into a 74 Dart Swinger?
