Battery wiring in the 40's

[parb]

Hi all,

What type of battery cables was used in the 40's for GM cars and trucks?
Was it cloth wire or did they have PVC/Plastic in this era?
I assume the ground terminal was the woven wire (all articles i've read seems to suggest that the ground was done as a ground strap and not a traditional wire.

I also read that 6 gauge was typical?

Thanks for any ideas. i'm about to start a restoration and i got most of my effort mapped out -i just need to get the wiring right.
