There appears to be lots of questions about...
What number is my 1995/6 DTM Turbo?.
You have two places to look
1) Inside the car on the ash tray cover
2) In the engine bay sitting on top of the relay box.
On mine, the relay box just has the plaque but no writing.
If your doesn't tell you your number, then I don't think you can get it. (I hope I am wrong)
Oh, if someone wants to take this image and make it better, please feel free too.
