That is a good question and most people would say yes however that would be incorrect. The United States didn’t start selling FJ25’s until 1958. Early 1958 models used leftover parts from 1957. Actually the U.S. did receive FJ25’s in1957. 2 from what I have read came in late 1957 for Toyota Motor Sales USA to show and sign up potential dealers. The others 6 were sent to Aberdeen Proving Grounds for testing by the military. I have personally owed 2 1958 U.S. model FJ25’s.
If you look at the 1958 U.S. sales brochure you will notice there are no kick vents on the vehicle. You will also notice the hand brake and transfer case levers are in separate locations like later models. That changed mid year 1958 and those 2 shared the same hole in the trans tunnel. Yours also has holes in the center of the dash for the vacuum wiper switch and early turn signal switch.
So to answer your question, I would say it’s impossible to tell for sure. Do you have the serial number?
