The original part number for the six volt Gale, Johnson, and Evinrude starter is 277311 but I don’t know if it has been superceded or not. Doing a Google search for that number might help.
’57 and later twelve volt starters have a different spacing between the mounting bolts than the six volt starters do so a matching bracket must be used with it. And being a Johnson, the bracket must also have the nib on it to mount the hood.
