Battery cable questions

The cost of buying a new repop positive battery cable is a bit crazy, i can make one of these myself. Got 2 questions for y'all though.

1. What is the gage used for the positive cable ?

2. What is the stock length of the positive cable from terminal to terminal for V8 A body cars 67-76 ?

Thanks
Matt
