[Nice Ride]

Ok, I now have all the parts to add the 2nd battery. I would like to use the bolt hole on the engine block below the alternator. Any idea what bolt can go in there and where to get it? This is where I want to connect the ground for the 2nd battery.

Thanks

8mm IIRC. I used the same hole. Any auto part store should have a selection of bolts. Make sure it is not too long so it doesn't bottom out and crack the block.
