Does anybody know a part# or source for a 6V early GM-style (on board) solenoid? All of the web sources I've found only go by make/model/year, but when I double-check the applications of part numbers that come up, they cross over from both 6V and 12V eras (e.g. 1949 Olds and 1969 Firebird are both listed under same part#). http://ecatalog.smpcorp.com/STD/#/vehicles/parts/num/SS-210?type=s BTW, this is for a '49 Caddy but I can't find anything listed for that (Cadillac had an extra relay built in to prevent starter engagement when the engine was already running that I can live without) Any help is appreciated.
