Ha ha! Got sidetracked with another project. Then a car buddy brought over a Q Jet carb for an overhaul from his ‘70 GTO 400. I like your idea of the strap around the battery.

Finally got back at it!! Your strap idea worked great!!! The cable is attached to the battery lead post with a S/S bolt, washers and nut. I think that makes a better connection than drilling and tapping the lead post material.
