Now I've got myself a Polo radiator, I need to work out how to fasten it!

The rad has plastic sides with lugs, each of which has a hole. My guess is that these take some form of self-tapping screw, but I don't to experiment in case I break the plastic.

Can anyone who's fitted a VW rad please let me know the type of fixings they used?

Thanks,

David
