Re: disconnect switch

Thanks for the comments. Have a quartz clock conversion so hadn't really given much thought to the problem you brought up with low battery & turning the old points style off but very valid. At any rate, I had already decided to do the ground interrupt.
As to location, on a V8 (and from pictures maybe 51-4 as well) Randy's suggestion is brilliant. Not even as much work as he mentioned because it won't have to mount far away and need a bracket. There is already a proper sized hole in the firewall (3/4 needed for this switch) in the perfect location. On my car the hole is unused but on most cars which have the front antenna, it's used for the lead in wire. Should be simple enough to re-route that lead in to an extra hole in one of the wiring grommets for those that might be interested in adding a switch.
Not sure yet whether it will need an extension to bring the knob forward to mount under dash per suggestion. The stem of switch may be long enough to clear the firewall carpet but haven't got my new carpet yet to test--That bending down to actuate may be an issue for those that don't bend well so an extension might be nice and very easy. A straight 5/16 rod about 14" long will mate nicely to an underdash bracket. Jegs even sells a kit for a push pull switch that might work.
Only downside I see at the moment is it will require longer cables--whichever side of battery you choose to install it in. I had already bought new cables so will have to get a new ground cable or strap and relocate the attachment point on engine to it's corresponding point at the rear of head.
