Side Post Battery

[RonNova396L34]

I am new to the bulletin board. I don't have a supercar but I share the same feelings about this type of car. Here is my question. I own a 1970 Nova SS 396/350 hp 4 speed that I bought from the original owner 2 years ago. The owner save the majority of the original equipment for the car. The items he changed were:Muncie to Hurst shifter, voltage regulator, rochester to Holley carb, and starter. The correct starter and carb are now on the car. He saved the original protecto-plate but the original window sticker he did not have. He said he never got it from the dealer. Now my question. He said the he ordered the car with a heavy duty battery which he said came as a SIDE POST battery. He swears on his good reputation that he never changed it and it truely came that way. The car was assembled the 3rd week of August 1969. He took delivery of the car September 18, 1969. I was told by someone that knows Novas, I won't mention names, that this battery was not available until May of 1970. I have a friend that also has a 70 396/350 Nova and his also has the side post battery. His though has a production date of May 1970. I'm hoping one of you guys can shed some light on my question. Have you seen any COPO or other supercars of 1969 or early 1970 ear with a side post battery? Thanks, Ron
