I have just noticed that I got a DLC code for the Fallout 4 rocket sent to a secondary xbox profile I use. I am not sure if the codes expire but am willing to share the code if there is someone out there who never got the car and is interested.
Reply to thread if you are interested and I will PM you the code when I am next on my Xbox. First come first serve! Happy for the mods to lock the thread once an interested party has responded.
Note: As I have said above, I don’t know if these codes have an expiry, I can only assume it will still be valid.
If they don’t have Fallout I don’t think they can use the code.
They can.
If no-one else wants it, I’ll give the code to my cousin as he never played Fallout 4.
Code should be in your inbox, just sent via PM.
If a mod sees this, please close the thread 
They were giving this out quite a while ago when fallout 4 came out . there was a ford truck with a design relating to fallout 4 . A separate gift from turn 10 . The rocket was given out regardless if you had fallout 4 or not . I t was a similar situation when Halo 5 came out . You didnt need halo to get the 2 custom livery mustangs gifted by turn 10
