SU Carb to Ruby Inlet adaptor
#2
Don't know of any "off the peg" suppliers for these, but it wouldn't be to difficult to make up your own with a bit of time and some basic workshop tools.

Here's one I made for my AG tourer. It was a piece of Ally plate about 5/16" thick (ebay would have this) You can make the big hole in the centre using a holesaw in a power drill. drill the two mounting holes to match the pitch of the manifold's holes, then countersink them and use countersunk Hexagon socket screws (Allen screws) to bolt up to the manifold; these will then come up below the adapter's surface. Once you've drilled clearance holes for the carb and trimmed the edges of the plate with a file and hacksaw, you'll be good to go.

As you can see, this setup uses a semi DD SU carb which came off a split screen Minor. I just cut out the centre section of the Ruby inlet and rotated  it before rejoining the bits together using a Manganese Bronze brazing rod.
