Slant 6 alternator question

Hello, new to this forum and Mopars. I purchased a 1949 Dodge truck that had the flat head 6 replaced with a slant 6. I need to relocate the alternator to the drivers side and I am not sure what year and what models had slant 6's alternator on the drivers side and where I could obtain the alterrnator bracket. Any help is appreciated.
Thank you,
Otto
