1969 Z28 battery cables

[marxjunk]

i have a case of those packard cables..all mixed makes..nothing really cool or rare...some are spring rings others are like these

i think the translation of that 4F-30..4f is polarity and application, and the 30, is inches..the assy line stuff ive seen has a complete GM numbers..but i am not even gonna act like i know for sure, just my observations

they come in green Packard boxes and where replacement stuff for gas stations and repair shops..some of the boxes have a long list of applications etc..BUT on the box it has a GM part number that i have successfully matched up to a GM parts manual..if ya want i will post a few pix..

also the packard boxes i have all the cables are black and no red..so pos and neg are both black, but the apps call out neg and pos..the hole is bigger on one..even the side post stuff they are all black
