How about scroll down the page to Clamp-on Couplings. Try 3084K51. You'd 
need to bore out one end to 3/4 inch and cut a keyway then get a 1.75 
inch OD bush and bore out to 1.778 inch, unless you can find a ready 
made item. MMC carry a_lot_of bushes. It might be possible to bore out 
both ends of a 3084K36. Depends how much spare there is.
