The 47 uses same bellhousing as my 46, has tiny trans pattern and mounting boss for master cyl/pedals. I solved this easily with an adapter- trans to Sag 4 speed. These adapters are around will need to search, Buffalo Ent makes these and other. The mounts should be in stock at usual vendors Jim Carter, chevs of 40s etc.
Best of luck

P.S. Found mounts at Rockauto.com under $10 ea.
