If you get a floppy drive with an ST-506 interface, then it won't have a 34-pin edge
connector.  Frankly, I wasn't aware that anybody made such a thing.  I'm dubious
about your identification of the 8" drive, since they were commonly made with
50-pin interface connectors, but not in ST-506 interface as far as I know.

Assuming that most of what you said was incorrect, you can probably get this
to work with simple cabling changes.  You may have to mess with the device
driver to get a suitable disk format.
