Hey all, I just replaced my fuel tank in my 48 D 24 Custom. I went to install my new sending unit and my new unit is a 2 pole sender and my original is a 1 pole. Any ideas on where I can get the 1 pole? It looks like in mid 48 they changed to a single pole design. My car is still 6 volt positive ground. I did some research and found only one reference from 2010 on the forum. Thanks
