big block bracket bolt question

[SkysTheLimit]

I'm looking for the size / qty of the bolts I will need to mount up all my accessories. I got a bracket kit off another member and it included some of the odd ball bolts but not the others. (like the ones that mount to the block)

Anyone know the size, length, threadcount, etc of what I need? It's the half serp half vbelt set up. The second set up in this thread.

I found this thread and it helped a little:

But not quite informative enough description of "bolt" on the gm website.

Thanks!
