I need to know if there is another ground besides the starter bolt ground.

I had dash gauges go out after tranny swap.

For some reason im thinking i remember seeing another ground.,..

 

On our race cars there is only one ground that mounts to the tranny. It's a braided ground wire that goes from the bellhousing to the engine bay. That's on our race cars though and most of our rx7s don't use the stock guages.

 

theres the ground that goes from the firewall to the uppermost tranny bolt.....not even sure what this does but it has a spade connector clip thing and must be removed/unclipped to get the tranny out.

not sure if this anything to do with your problem i just know it's there

Which gauges? The power and grounds for the stock gauges are in the cabin, and would not be touched during a gearbox swap. However the sensors for the temp and oil pressure gauge are right next to the gearbox...
