Side Post Battery

[Mr70]

Chevrolet started using the Delco R-79W side post battery on their cars in late 69.It was available on the Camaro too.I am not sure about any COPO's receiving it though.
I have an two NOS side terminal Batteries still in their boxes,and both are dated July 1969.
Now when Chevrolet started installing them in cars,and what cars and what plants,and what time frame is a diffferent story.
All the 1970 ordering books and catalogs mention this new side terminal battery for the new cars in 1970,which by the way were annnouced to the public September 18-1969.
I have seen 1969 Camaros produced in Late 69,1970 Chevelles,Monte Carlos, and Impalas/Wagons have it as early as August 1969,but I am not about Novas.
Just curious,where is your current battery ground too,the block,or the Alt. Bracket?
I have a box full of Chevrolet MSO,Window stickers,buildsheets and Dealer invoices from 1969-72.I have not been able to get to sort them out.I will look for 1970 Nova specific and let you know what I find.
Your 3:31 rearend intrigues me,as the Chevelle did not get the 3:31 untill Oct 69.I have not seen one that early in a car as yours.3:55 was the norm,then the 4:10 was the optional.Is yours dated on the housing?
