Gary Lewis Posted February 12, 2021 Share Posted February 12, 2021 I'll check those ID #'s to see if I can cross to part numbers - when I finish this cup of French and make my way through the COLD to the shop. Link to comment Share on other sites More sharing options...
Gary Lewis Posted February 13, 2021 Share Posted February 13, 2021 Sorry I forgot this yesterday, but here they are: ID # D9TE-10039-BA is part # D9TZ 10A313-A and it was used on a bunch of the Bullnose trucks with the 300 six from 1980 - 84. You can confirm that it fits your truck at Documentation/Electrical/Alternators and the Part Numbers tab. ID # D9TE-9B484-BA is part # D9TZ 9B452-B. HOWEVER, that is not an alternator adjusting arm. Instead it is an ARM (EXHAUST AIR SUPPLY PUMP BELT ADJUSTMENT). An alternator adjusting arm would be base part number 10145, not 9B452. Link to comment Share on other sites More sharing options...
