1969 Barracuda 340 Formula S Restoration

I pulled the alternator off the engine to check it before taking it to Dixie Restorations. Found it is completely the wrong one!!! It is a 1966 alternator 2098830 which is a standard 35 amp.
I instead need a 46 amp 2098850 (preferably date coded in the latter half of 1968). If anyone has one, I'm interested!!!
