What are my rear shock options ?

[Freza]

OK, I found a brand new R6 shock here locally, it's from a 2006-2007 R6, for 150 GBP.
Is that ok?

But now I have a problem with dogbones and tophats, where do I find that?

There are always top  spec options too like nitron (recommended) or ohlins or hyperpro.

Unfortunately I can't buy those here where I live (Croatia), which means I would need to order them online and prices are not very friendly :/
