I also had problems with vin and engine #'s, so I did a search on yahoo using the make and year of my truck and the words vehicle identification numbers. A sight came up with all that info. but I still could not find my vin plate. It is missing. However the engine # on the flat sopt behind the dist. of F56Z reads F-flint, 56- 1956 and Z- well mine was an x so I dont remember what z was. Hope that helps.
