Serial number help !

[74fj40Oregon]

Hey all I’m in the middle of pulling the motor on my 74’ fj40 and going to start ordering some parts and pieces to do a full rebuild. Curious if anyone knows if this will be parts for a F motor or a 2F ? I have heard that it’s cosidered the F.5 but not sure if it changes what I order ? Thanks for the help
