I have a ASTRA MK4 1.6 TWINPORT SXI 2003 - I need to find out the engine number/code? (like z20LET etc)
I didn't get the car passport with car so dont know how to find out. this may be a really stupid question???
The reason is im planning on fitting an box to my car - need an adaptor for my sleeve fit centre pipe to flange fit box. do one but have said its not suitable for a 16ZNR??
