Nearly everything that I bought "cheap" has been replaced.
Some things however are best bought 2nd hand.
Most of the new chrome items have started showing signs of rust and have been returned. I bought a set of "new old stock" door handles and they are still as good as new. Good old chrome is much better than new chrome.
Have a look here for lights

I used the same indicators as Casamolino, look great and I think they are stainless steel. No rust yet!
