I'm definatley not a Muncie Guru, but have had a few of them over the years, and have one in my '55 pickup now. I'm wondering if the stud is an integral part of the shift shaft or a screw in stud? The one in the reverse shaft in your newer one has either been replaced or the stud was unscrewed and a bolt substituted. If the broken stud can be unscrewed out, you are home free. I would think that the shaft with the broken stud can be drilled and tapped, but the tranny would most probably need to be removed from the truck and disassembled? Wish I could be of more help, maybe a Muncie Guru will!
