Pulling Harmoic Balancer - What Bolts

[Kaiser Pontiac]

Hey, so, does someone have a link where I can buy to what bolts I need? I have access to pullers, but not the right bolts. I was told Grainger might have the right ones, but the set I was linked Grainger doesn't have.

L67, BTW.

From here: "The actual size of the threads is 1/4-28. Not such a standard bolt thread but thats what it is and I think they need to be 3-1/2" long or thereabouts." So, I could actually just buy three of those and be good?
