Default Ballast Resistor

Hi, this may have been posted before but I an trying to get a picture of an "original" 63 340 hp black dot ballast resistor. The repo's are stating they may not be NCRS correct. Mine is a Delco-Remy but there is something to do with the attatching tab that might not be correct (notches). I would put a picture of mine on here for varification but I am not good at posting pics, thanks, Greg

Photo below is an original '67 resistor, and the second photo shows one version of the "tab" sometimes seen on the bracket resulting from the progressive-die stamping process. There was no "black dot" PRODUCTION resistor - only the 0.3-ohm Service parts got the "black dot" after the release of the 1.8-ohm "blue-stripe" resistor in February '63 (only for 250 & 300hp engines).

Thanks John, I'm sure you would know. Funny how the new NCRS judging manual says the L75 engine has the blue stipes and the L76 and L84 have a black dot. I am thinking that little sticking out piece on the attatchment part is what they are using to say it's a replacement part, Greg
