Can Someone Identify This Transfer Link For Me?

[Ironhorse]

Thanks for the added information on the flat link. Guess will toss it back into the tool box and think on it for a bit as to keep it or let it go. Very doubtful I will ever need it as a replacement and don't think I will be building another K truck. My build days are just about done at 75 years young. Body just doesn't play as well as it used to.
