Does anybody make a car battery that has external connectors (buss) between
cells. If I remember correctly all batteries use to have this back in the
'50's ±.

Here's my problem. I converted my 1948 Pontiac to 12 volts. All bulbs have
been changed along with the ignition coil and the alternator. (6 volt
starters LOVE 12 volts. Spin real fast!!) However the standard solution to
run the gauges is to install a giant drop resistor. Seems to be an
inefficient way to handle this.

On old batteries you simply drove a sheet metal screw into the lead buss on
top of the battery and tapped as many cells as you needed to get a lower
voltage. Can present day batteries be tapped somehow? Any ideas?

Thanks,

Use a large 6V Zener in series with the load. Depending on the
current use a good heatsink. Very easy.

A zener does not make a good series regulator Lew.
