I have been having trouble finding a temp gauge for a 1941 160. Dose anyone know of a aftermarket gauge that has the same threads as the packard head?

If you are looking for a complete gauge assy to use while you find a factory 41 gauge I was able to get a no name inexpensive unit off ebay that came with adapters, one of which fit the 47 356 head. As I recall that head port has a 5/8 thread and I think it is 5/8-18 but been too many years so won't swear to that. Dorman has several relatively inexpensive gauge kits that come with adapters and one of those might fit. Lighted gauges are probably 12v LED so that might be an issue if you wanted a backlighted gauge. If the port is open waiting for a sender you might confirm your port thread size by picking up a 5/8 bolt and see if it threads in.




Alternately, Amazon also has adapter only kits that might have what you need but sometimes a brand X sensor has proprietary threads which might not fit a brand Z adapter.




Amazon also sells AutoMeter individual size adapters but while the given specs at Amazon are full of useless info such as weight and box dimensions, actual thread sizes don't seem to be given so if buying one of those you would need to visit the AutoMeter site and see if you can find thread specs by part number.
