Standoffs for PCD-50B

[madgrizzle]

I'm finally putting the case back on my 2000.   What suggestions do ya'll have for raising the height of a PCD-50B mounted in the left floppy drive bay?  If I mount to the base, it's too low for the case.  I can't seem to find the right standoffs that fit into the bottom holes of the PCD-50B.  Are they available?  Is there a recommended 'hack'?  

Thanks

Thanks.. i found a mechy thread indicating the threads were 4-40.. found some 4-40 3/4-inch machine screws and 8-32 nuts (used as thick washers) at the hardware store and it worked well.  Three 8-32 nuts raised the reader to near perfect center line of the floppy.
