GEC duplex

[Cleveland Apprentice]

Hello,

I believe this was addressed here before,

I am looking at a duplex and owner wants to update the two (60 amp services) to 100 amp CB. The two services and MB are opposite corners of the structure. I plan on running two ground rods (one for each service) and I know that I have to bond the two together. I am not sure if split bolts are permissible to bond the two GEC's or if I have to use an irreversible clamp. I'd like to bond them together inside the basement ceiling so I don't have to dig a trench on the exterior. Can I use the neutral bar as an approved bonding method between the two panels and run the GEC out to the rod from each panel? Also I didn't forget about the water line which is copper. I should know this but rarely work on duplexes.

Thanks in advance

Boss thinks ok to use split bolts between the two but it doesn't seem correct. Not trying to undermine him but I kinda question his logic on a few things such as this.

I have found my answer thank you.
Also, I am no longer an apprentice, now a journeyman but not sure how to change my forum name. Thanks.
