As there were no 67-72 trucks with internally regulated alternators, the simple answer is it is designed for a externally regulated alternator.
When you change over to a single wire alternator or the American Autowire kit,, the wiring for the amp gauge is not supported any longer.
The way around this is to add my volt gauge conversion for an additional $100.00. The volt gauge only needs battery voltage (from any source) and a ground to show actual battery voltage in the system.
Hope this information was helpful.
Take care,
