Battery cable lengths for 1970 C20 V8 with AC

[OhCookie]

Hi all, I have been doing research here and and can't seem to find a definitive answer. I would like to know the correct battery cable lengths, positive and negative, for my 1970 C20 V8 with A/C. I need to replace them and would like to order the cables beforehand.

I also searched the GM parts wiki but I'm not sure I am reading it correctly. I came up with 28'' for the negative and 58" for the positive cable.

Can anyone confirm or deny this?

I believe 1970 was the last year with a top post battery.

Here's what I'm using on my 350 '69 C20 with A/C and top post battery in the original orientation... posts toward the radiator support, positive toward the fender. I still had the originals, and these were the closest match. The negative 20" cable runs to the front most exhaust manifold bolt along with the A/C compressor bracket. Wouldn't hurt if the negative were an inch or 2 longer.

EDIT: Incidentally, I think I still have the original cables if you want exact measurements.

If originality is desired, the spring ring cables are not correct for our trucks. The spring ring cables were, however, used on cars of this vintage. Here's a couple pictures comparing the terminals on the cables I posted above to the originals from my '69.
