nope.. it's a naa/jube only deal. the 55-64 machines all took a different one.
that one has a tube ont he bottom for a single bolt going along the plane of the bracket, and that lip ont he back hookes to a flat plate that is sandwiched under the steering box... a jube has no upper holes in it's bellhousing like a 55+ does.
a bracket for a 55+ has 3 holes. 2 at the top for the top of the bellhousing at the squared off boss where the sn is, and a lower single hole. all go thru and intersect the plane of the body of the bracket, vs running parallel to it.
it's a nice find.
like I said. it can be duped.. i helped someone dupe one.. but it's nicer to find one premade.
and the brackets for the jube, 8n and dexta are virtualy unobtanioum nowadays..
