Which 9psd deraillieur with Shimano SL-M751 shifters ?

I recycled the rear mech for my (approx 2003) Marin Mount Vision a bit too eagerly after ordering a new Deore rear mech only to find it just shifts 7 of the 9 speeds. i.e. Doesn't move through enough of an arc to reach all the cogs.

Now I have no idea which rear mech to buy.

Doh!

The front shifters are Shimano SL-M751.
Is there a 'deraillieur --> shifter' lookup table anywhere?

Cheers.

    What a plonker...
    Note to self: Check limit screws when fitting rear mech.
    Now fixed...
    I did read an illuminating post on cyclinguk about sprocket pitch and shift ratio.

    There is no logical reason why your Deore mech won't shift to all 9 sprockets, sounds like a setup issue.
