I'm in need of a new battery for my '70 Z28 and want to buy the correct battery. Do I need a top post or a side post or does it really matter? Thanks.

The correct battery is the R79 side post. I believe this was the first year for the side post.

Side post batteries were available on camaros late spring of 69.

Thanks guys, does anyone have pictures of the battery and cables? Most of the engine conpartment pictures don't show the battery up close. http://www.yenko.net/ubbthreads/images/graemlins/biggthumpup.gif

Not the greatest picture, but all I had on hand.

Speaking of batteries... where can I find a new screw to connect the battery cable to the battery?
The one I have on the '70 is badly stripped and needs replacing.

Thanks Jack, that helps alot. it looks like the negative cable is streched a bit, is that original? http://www.yenko.net/ubbthreads/images/graemlins/biggthumpup.gif

These Originally had 3/8 Positive terminal & 5/16 Negative terminal outlets.In 1971 when the R89 replaced this battery,they used 3/8 terminal outlets on both.

The different size pos. and neg was to keep people from getting the cables crossed, with the new side post batteries. Didn't take long to go the same size for both. This explains why the negitive end of my original cable was cut off and a univeral clamp on type was added. the first time the battery was changed they had to.
The negitive cable is a reproduction, but it's the exact cable and length and number as the original.

Bet a lot of owners/garages did that when replacing these batteries back then.I still cut the Neg. cables off the 1970 vehicles,equipped with side terminal batteries,if I see them in the bone yards today.
The guy I bought this from told me his parts counter buddy got this Battery for him,because he noticed they were phasing out the R79 for the new terminal R89 Battery.
It sat in his Basement for nearly 30 years.
