WTD: 1" Rock Shox steerer

[simon_adams_uk]

I'm looking for a 1" steerer+crown assembly for a pair of Rock Shox SIDs - I suspect that a Judy crown would also fit. Specifically what I need is:
* >160mm 1" threaded steerer + crown OR
*>190mm 1" threadless steerer + crown

Am happy to either buy or to swap for a 175mm 1" threadless steerer + crown.

Thanks in advance,
S
