Rejoyce! Another job that is quick easy and makes a big difference. While the price of the alumininum radiator brackets can't be described as cheap, they are well worth it when you consider the effect they have and that they take 5 minutes to fit
You will need:

A 12mm spanner or rachet and socket An allen key
Take your 12mm socket to the bolts on the old radiator brackets and take them out. The radiator brakets only limit the front to back motion of the radiator, so removing the brackets will not make anything fall off. Take them off and remove the black rubber inserts, we're going to reuse them in the new brackets Put the rubber inserts into the new brackets with the largest part on the bottom. Then place the adapter sleeves (small tubular things) that come with the brackets on top of the bits sticking up out of the top of the radiator
Now place the bracket over the adapter sleeves and put the bolts into their holes. Tighten these with the allen key and you are done
