Went to get the new exhaust fitted today but they didn't have any clamps of the right size, and the old ones were unusable, so have to go back again

Mechanic had a look round at my request, and my questions are
1. bushes are on their way out so I guess I'll have to replace the wishbones. Was going to get them from VSC on Ebay due to previous recommendations from members. Any other options?
2. do the droplinks have to be changed at the same time?
3. he also mentioneed a steering component would need changed. Can't remember the phraseology but he said it was on the passenger side and bolted to the chassis leg. It was allowing play in the front passenger wheel. What is he referring to?
4. he also suspects the followers are causing the tapping noise rather then the EM gasket. Anyone fancy doing a 'how to' for removing the cams and followers? The one for cam gaskets goes so far, and there is one for checking the followers themselves, but nothing in between. I think VSC also supply new followers.
Think that's it for now! Sorry about all the questions, and any advice, as always, is gratefully accepted.
Cheers
