Joe, Further to my first response.
I just looked at one of my Spare Parts Catalogues pages 15 - 16 and it says
the ZS's were fit up to Engine No ..................... and to see pages
17-19 for future. Page 17 says fitted from Engine No .............. but I
guess the service garage was to fill in the ..................... space
since no Engine numbers are provided.
Best that I have, someone may know more.
JVV
