Anybody have a Napa or Dorman number for the Packard freeze plug number 320578. This freeze plug was used on 1938-1954 Packards. Thanks

Most engine reconditioners should stock these standard freeze plugs. In the 40+ years of use by me my 120/1938 has used several, but that's in New Zealand!

Utilities section 50.810 gives the 320578 dimension as 1.958. Using that number it would appear there might be three or maybe 4 choices from Dorman that are in the ballpark. Take your pick.
