clutch fork pivot question

I need the dimensions for the clutch fork pivot in an a833od bellhousing. It looks like it should be similar to the one in my '62 3 speed bell, but I don't know if it is interchangeable. the fork has a groove across it and a metal tab riveted in to hold it to the support. I do not know what year it came from or I'd tell you that. I think if I can find out the height of the support and the size and position of the hole I could make one.

Thanks for any info you share
