PRE - 9/10speed KMC chain & I had a Dura Ace R-Mech floating around..so snapped the chain put i on it etc..but the indexing would never index absolutely correctly anyone know why as I'm gonna have to put the Tiagra one back on which will index proper !

If it's an old (like, really old) Dura ace I think they had a different cable pull ratio. Check on Sheldon - there's a different cable routing that *should* make it work with new stuff.

7400 series and older Dura Ace have a different pull from the rest - will only work with DA shifters

Yes he's right, pre-97 Dura Ace, before it went 9sp

You can use a newer non-DA derailleur with old DA shifters by different cable routing, *but not old DA der with newer shifters* like you're trying to
