Does it look like an original?
How is the depth? I have one of their 30 amp ammeters. I have not installed it yet, too many other things going on.. It looks pretty long.
The depth was fine. The only real difference is my old gauge had the terminal connections on the rear of the gauge and this one has the connections on the top. Depth wise it fit fine.
How about diameter? I've told about my high quality appearing ammeter which ends up is a skosh (technical term) "small" for the dashboard hole. Solved by me by backing it up with a stretched O-ring for the bend/ears to seat against.
These go back from about 20 years ago.
