Both NOS.
Part number for speedometer:C5AZ-1725-A/C5AF-17265. $150. The needle has some of the orange paint chipped off and the base of the needle has black paint chipped off from the needle being bent at some point.
Part number for the fuel gauge:C5AZ-9305-B/C5AF-9306. $100
Both fit 1965 and 1966 Full-Size Fords (Galaxie 500, Custom, XL, LTD, 7 Litre, Country Sedan, Ranch Wagon, Country Squire, etc.) Double check pics and part numbers to make sure these are what you need.
I also have a lot of other NOS and reproduction parts for 1965/1966 Full-Size Fords.
