Need stud part number for 904 output

Did the driveshaft conversion on my 1965 barracuda and everything went back together fine. The trans was rebuilt a while back and whoever removed the driveshaft did a little damage to the studs on the output flange of the transmission (the flange that the trunnion joint attaches to). Does anyone have a part number or dimensions for those studs. I'd like to have them on the shelf. Thanks.
