Does anyone have a source for a 223 alternator bracket? It has an alternator installed, but the current bracket vibrates a ton.

 

Since alternators were not available until 1965 (excepting 1963/64 T-Birds), there are no alternator brackets listed for a 1962 in the 1957/63 truck parts catalog.

223's were cancelled at the end of the 1964 model run, so there is nothing compatible 1965 and later.

This is the typical sad scenario of what happens when peeps swap parts, and don't record what they came from.
