sitting on fence about amp meter

I wish I had taken pictures of it, but it was before digital cameras. I mounted a small digital voltmeter in the ashtray, did the bulkhead connector bypass, disconnected the ammeter and left it in the dash so it looked stock. Lately, I've been installing digital voltmeters in Piper airplanes. They came with 37 amp Chrysler alternators and many are upgrading to more powerful alternators for better lighting and upgraded avionics and are also having the same problem car guys have overloading the ammeter which is very expensive to upgrade or repair.
