What yoke for a “78” driveshaft

Hello,
I need some help on a driveshaft yoke for a 1978 Plymouth slant six. I'm putting it in my 1951 International
pickup. If any body knows the parts # or what will fit it.
I have to get a driveshaft made and I need to know what I'm looking for.
Thanks for the help.
