Yes the stock bolts will work, I recently put the split mono's and caltracs on my 66 nova. The diameter of the front bolts I believe is 1/2" but one side of the hanger /factory bolt is 3/8". I just drilled it out to 1/2" and got some 5" long 1/2" grade 8 bolts. My factory bolts were trashed . If you want to keep the factory's Idea just order some new bolts from Year One or Ground-up, Their cheap.
Did that make any sense ????? Even I'm confused now.
