Yes - we have a selection of springs
I personally prefer the original Schaller made ones but they are a bit flexible
The Gotoh ones are stiffer and can work well if you are using a heavier gauge of string
As far as needing to get the fine tuners, I will check but you may need to get a whole new baseplate.
There is a bit of a problem of late getting Schaller stuff but I can take a look in the spares box when i am back in the workshop proper...
I am hoping in time to get more and more Floyd parts and accessories as there doesn't seem to be a single reliable source you can go to, and I think that many players would benefit from an expert supplier.
I am setting up a dedicated offshoot website from the main Feline site, just for Floyd Rose -
It will be for both sales, spares and accessories, and a resource of information and templates etc
I am indebted to young Afghan for his help so far with this and will keep you posted as soon as he and I get the site up and running.
