For my felica estate.

Rear left shock (the spring seat as rusted off and now spring sits on arm)

Gasket between CaT AND HEADER pipes.

The two bolts that bolt the cat to the header pipes.

Where is the best places to get these from?

GOt the shock, but what about the gaskets?

Have you tried butts of bawtry? They were very good when I had my Favorits. I think its garage equipment, skoda parts, leister hot air tools, workshop equipment, ravaglioli but if that doesnt work a quick google should throw it up!

If not, I should think a good independant little exhaust and tyre place should be able to sort the exhaust for peanuts, I know mine wouldn't charge more than a tenner to sort that out.
