Fitting a new radio in a 1988 UK Vauxhall Astra

I do hope some of you can help me. For my girlfriends birthday I bought her a cd/radio player for her car. The problem is I can’t get the original one out. Unlike a newer radio there are no holes that I can stick the two metal bits in to get it out. I’ve undone the screws around the dashboard but I still can’t get it out. I’ve tried pulling it out but it just seems stuck in.

If any of you can help I’d be really grateful.

Thanks.

Doesn’t matter now I’ve managed to do it. And what a pain it was.
