Is it something I can do on my own or do I need someone with me to shout at when it all goes wrong. Do they go back on ok or it is a real problem to get them shimmed up etc?
Easy job, possible with one, better with two.
Remove wheel arch liners and don’t forget to disconnect the wiring for the lights at the connector. Also replace the nasty original jubilee clips on the radiator hose while your there.
Yeah I would say about an hour each way. It’s not a hard job at all. As has been mentioned, its a good plan to replace some of the rusty fixings with nice new stainless ones as well.
