i just bought this autometer gauge off ebay. and when i go it, it had this huge AN fitting on the end. now most gauges i have installed on a 350 block use a 1/2" npt nut that screws into the head and then uses a 3/8" npt sealing nut to hold the sending unit in. can someone tell from these pics if i can use this set up, or if i can take this AN fittin off somehow to use the more traditional set up.
