This is a new, never used torque converter. I purchased it from the vendor here on EBay. It was to be installed in a 1964 C-4. However, the early C-4s require a shorter snout. This unit was filled with fluid but never run because it would not fit the C-4 in my '64 Fairlane. Rather than pay a restocking/exchange fee, I'm choosing to sell at a loss. It should fit all C-4s from 1965 and up. Item sold as is. No warranty or return. Thank you.
