How else would you mount it?  :-)  Lots of the stuff they sell was made
for use without encoders.

...unless you find what you want in the catalog.  They will put encoders on 
some of their motors; they have some with encoders on them already.  If you
buy surplus, you have to know what you are looking for, so if you're not sure, 
buy new.
