ARP bolts

I,m ready to put the eninge & box back in the duster & I,m replacing the standard flexplate with a B&M one.
On inspection of the ARP flexplate bolts I noticed they had been shorten with a grinder & are a bit damaged.
Having trouble locating the part number of the ARP small block ones, they are 7/16 but have need cut up so I don't know the length.
These are 440 ones ARP Pro Series Flexplate Bolt Kits 200-2903
What's the part number for small block?
Better to be safe than sorry
Thanks
