Hot-Wire Diagnostic System

[Griffith430]

To check my griff430 twice a year I am using the original - Range Rover Hot-Wire Fuel Injection Diagnostic System - which I bought quite a while ago. It is not available any longer so far as i know. My Problem: I have lost the two chip cards (A+B) which you need to run the system. Does anyone know, where I can get them. Since there are different ones, I need the cards for "Range Rover 3.9L - 4.2L"

cheers
