Be advised that the popular GM alternator used for "one wire" conversionss requires more rpms than the old cars can provide at idle. We made a smaller pulley for it, but still have to use high engine speed to turn it on. That requires very tight belt tension which is hard on the water pump bushings. I finally installed a push button switch to kick it on.
