You should be able to use the mech from any laptop Zip module as I'm pretty sure they all use the same Iomega-made mech(s). Personally, I wouldn't go for the D-series module, in your case, as you should be able to find a C (Inspiron 4000/8000) one (like this) cheaper.
If you do get the D-series one, though, save me the rest of it.
