Lonnie,

I did not think to check the Factory Assembly Manual.
While looking at it, I noticed the prior page, sect. 12 sheet 7.01.
It shows a Ground strap on the driver side of engine also.
Driver side of Engine Ground Strap

The hydra-matic 3100 truck passenger side ground strap, was repositioned to the back side of the bell housing.
Gnd Strap HM
Compared to Manual tranny truck.
Gnd Strap Manual Trans

So that means there is:
1 Flat Ground strap for battery.
1 Flat Ground strap for passenger side of engine.
1 Flat Ground strap for drivers side of engine.
1 Flat Ground strap for Radio, valve cover to fender support arm/brace at fire wall.
A total of 4 Flat Ground straps.

There must be a reason to have 1 Flat Ground strap on
each side of the engine as opposed to putting both on
one side of the engine and stacking them together.

Thanks, For the info
