64 Voltmeter Gauge

[1964SS]

Good afternoon to all,

I looking for a replacement Voltmeter Gauge to fit in stock instrument cluster to replace the stock ammeter. I ran by an old thread that mentioned a member on this forum that goes by T Bone makes them. He has updated his contact information in 2020 but I haven't seen a post that included him in years. Does anyone know how to achieve this replacement or if
T Bone still makes the gauges. Any help is greatly appreciated!
