alternator (wire shield?)

[EccentricMagpies]

is this part needed?
I cannot find the part on-line... battery side line

i can see the importance of it i guess. but the wire was cut or broke off.

(i know.. poor photo too)

[EccentricMagpies]

as you would see here....

Found the part I need. 

Probably do without it though since it's not really even needed.

[John_Kunkel]

Its purpose is to prevent inadvertent contact with the live terminal, not uncommon when performing maintenance.

[EccentricMagpies]

i understand that.  Other than a complete wire harness, I have not seen this part w/ wire sold as as separate item.  I've seen some insulators that bolt on after the wire is attached which I suppose would suffice

[EccentricMagpies]

Wait.  That old piece would still work

[Nacho-RT74]

yes, you can cut it and use it like the repro piece, sliding it into the alt stud with the eyelet terminal of the wire making the slot
