Hi Ed,
good luck and please let us know how you get on. Take your time broaching out the holes so that the bush just starts to go in and then hammer it home. We are here to help whenever you need it 
With the staking set, it is a useful tool and there are times when you will need it but you can often find other ways around things. If you see a good set come up cheap then grab it but at least now you can take your time and find a good one at a good price.
Paul.
