Im trying to help my grand father and believe I need a bonding screw installed. (he has neutrals and grounds on the same bar)
Can anyone please indicate where it goes on the main panel?
If you could highlight the location on my attached picture, that would be much appreciated.
Thank you!
The panel you have pictured is a grounded panel but originally designed for just 12 branch circuits. There would be no problem if you added an extra ground buss as long as it is screwed securely to the metal box and bonded to earth ground with a piece of 10 or 8 AWG. Knowing you want to add kitchen circuits, looks like you have plenty of capacity. Minimum of two 20 amp convenience receptacle circuits (GFIC), one for the fridge, one for the dishwasher, and one for lighting. Looks good to me. I'd pass it on my inspection.
You'd have to remove the bonding jumper, and install a separate grounding bar.
Notice in this image, there are clearly separate grounding bars installed.

You should be good to go already
According to the diagram on the labels inside the cabinet proper, the furthest-right screw position on the neutral intertie bar is where the bonding screw goes, and it appears to be already populated in your photos, as it should be.
