Clutchfork pivot point bolts?

[Basoline]

Ok, which bolts to use to tighten the clutchfork pivot on my bellhousing?

Bellhousing is from a 1969 B-body, 11"...

Thanks!

i cant remember 100 percent but i believe they are 1/4" diameter by 1/2" long and i cant remember the thread pitch, i want to say its 20. if its not 1/4 then it will be 5/16. you may even be able to fit a 3/4" long bolt in it
