OBD II or EOBD as it's known in Europe is a standard which applies to engine emission data only. Your EOBD scantool is very unlikely to give you much or even any information relating to manufacturer specific data. It'll only be good for emission data, which on another day would prove perfectly useful so don't get rid of it. But I'm this instance you will need to find someone who has a suitable scantool for Vauxhall.

an op-com would work great on a classic of that vintage, I would think.
