The brackets like BobC posted should be fairly easy to fab or have fab'ed. They do not mount flush to the block. The ones Bob posted used different size spacers, the mounts themselves can also be machined to fit (like the ones posted).

Also, the photos of the mounts with the spacers have a modified steady rod, it threaded further down the rod and a nut used in place of the forged flare on the originals. My guess would be they ground or machined the flare off of the steady rods and then extended the threads. That would make the length of the steady rod from the frame mount to the mount easier to deal with.
