The car had a tractor battery in it that actually has lasted about 9 years.

Looking around for a replacement that will fit with some good CCA.

Looked at the Optima and it looks great.  But they don't sell one that fits the car.  It's actually quite a bit smaller, especially width.  And a bit pricey too.

The local Farm store has a 6 Volt with 900+  CCA.   It actually seems like a near perfect fit for the battery tray.  Dimensions are 12 1/2" x 6 7/8" x 9 1/2".

I measured the length and width of the tray and it looks like it fits.  I'm a bit concerned about the height.  Measuring it the best I could it looks like there will be about 2 1/2" clearance from the bottom of the hood to the terminals.

Can anyone tell me the original stock battery dimensions?  And/or if this will fit?
