2004.5 were made late 2003 through summer 2004.
The VIN number is what determines whether it's a 2004.5 or not - assuming you saw the other posts on how to identify one. If not, here for the millionth time...
2004 Nissan 350Z Coupe/Roadster (Coupe VINs up to D*4T160000,E*4T060000) (Roadster VINs from D*4T102001 to D*4T110000 & from A*4T002001 to A*4T010000)
2004.5 Nissan 350Z Coupe/Roadster (Coupe VINs from D*4T160001, E*4T060001) ( Roadster VINs from D*4T110001, A*4T010001)
If the letter before the 6 digit serial number is "M" instead of "T", it's a 2004.5 because it was produced at the Oppama plant.

6/03 and after is considered a 2004......2004.5 in reality terms does not really exist. Like when i order parts for cars i dont say let me get a thermostat for a 2004.5 350 z. Usually what Shariff is saying may be true, but the Up Widebands are usually found on the California Emissions Z's in the beginning but they went all around in the newer year makes.

personally i never really look into the differences only due to the fact that if there is some kind of problem i go through the schematics that are already done up for me so i never really notice differences unless i work on the same type of car/problem daily or repeatedly you know. Might happen once every few months to never at all. Unless it is a common issue on occasions. But next time i get a Z in i'll check the differences and compare it to mine as well.

The simplest way i have found is to locate the O2 sensor connection in the engine bay, passenger side is easiest to get to if the plug is rounded at corners and has 4 prongs its an 04. If it has 6 prongs and plug has squared corners its a wideband O2 sensor and must be a 04.5 or later! (also useful to know if you ever want to replace your O2)

WTF are you talking about????? In January of 2004, production moved from Togichi to Oppama. No 2004 models were ever produced at Oppama. There's nothing more definitive in determining a 2004.5 than the "M".
BTW - if you don't have physical access to the car, what use is the O2 sensor connector? With the VIN, you can always tell.

My vin checkes out using those guidelines to be on 04.5 but my vin # has a T. Recently i had to replace my O2 sensor, since they changed to wideband this year i had to take my vehicle to the nissan dealership they ran the vin and came back with corresponding replacment part numbers i then contacted Bosch and they ran the numbers to match with there OEM replacement it matches to the 05 wide band O2 sensor to confirm that i then sent a photo to Z1 Performance the plug in the 04 and 05 are different they confirmed i have a 05 wideband sensor concluding it must be a 04.5 so i would say that "M" or "T" are not defining factors of the year!
