Hey I am looking for a replacement ammeter gauge for my 74 duster. The current one looks to be in pretty rough shape and melted the plastic between the two posts as well as some pretty heavy corrosion on both post. Already have the gauge cluster apart so hoping to replace it.

Picture for reference.

You should look for a water leak above the amp gauge location. Wiper pivot or windshield gasket. It can damage your headlight switch also. I shipped the only used gauge I had to a 73 owner here a couple weeks ago.
Beware of sellers offering this amp gauge.

The 76 model gauge looks nearly identical to yours from the front but it is a totally different one year only animal, and will not work.
Yep your read between the lines that ma mopar finally did change this gauge because a water leak would shut down the whole car. Sellers dont know the difference and offer a gauge listed for "72 through 76 model".

It did have a leak previously, car is garaged only now and I am replacing the wiper gaskets since that looks like where the leak was. Your right it did damage the headlight switch too that what im tore it all apart.
 
Safest thing to do is disconnect the Amp gauge completely.
They have been known to start fires.
The description of your gauge is typical.

Their stamping dies wore out over time so the A-body panel fitment and and water leaks continued to get worse. The headlight switch and amp gauge always were subject to water damage in this model design due to their location. Hindsight is 20/20. The did change the amp gauge for the final year of a-body run. To replace this and that is only a fix. It will have the same inherent problem. So a "repair" to OEM has a expiration date. A forever correction requires added shielding. Something to keep the water headed to the floor and away from the electrical. A piece of butter tub attached to the panel to guide the water away from the instrument panel and the fuse box? I mentioned the fuse box because of water damage there in many similar A-body models that have the amp gauge located several inches away ( like my 67 with a rallye panel and different fuse box in the same location ).
And about those wiper pivots... They dont rotate 360, only 180, thus the wear one sided. Before you take them down, mark the bottom with a sharpie. When you reinstall, rote them 180 ( your marks to the top ). This puts the load on a less worn wall of the 2 little bronze bushings inside the pivot. I never was happy with Mopars wiper mechanism inside the cab but I am thankful for their simple/symmetrical 2 bolt pivot mounting. I can have smoother quieter wipers.

They aren't all the same. Some amp gauges are better made than others and well away from water damage too. Even though... There can be a totally different design flaw and good reason to bypass the amp gauge or convert the amp gauge to a volts gauge. Such is the case with a-body rallye panel (That conversion is more complicated in some models than others also). No need to get into all of that here. Some owners are willing to live with a in op gauge in their instrument panel while others are not. Good luck to all
 
I My have one let me look And it's not a leak.. The problem is over time the current that flows thru them makes them expand and contract losing the connection and there for making it heat up melting the gauge. That was Mopar's Mistake that is why they read in Volts Now not Amps
