Help! Need Output Flange for B&T 4-Speed

Anyone have this Flange?
I bought the wrong one from a member here that has a 4 1/4" Diameter (Pictured Left)
The One I need is 3 3/4" Diameter (Pictured Right)
it's for a 1965 Ball and Trunnion Barracuda 4-Speed w/ the 3.09 gear.
Mine is badly pitted in the Seal area and the threads are all clapped out...
Would also Send you the larger diameter one if needed
