an electrical nightmare , please help , 1972 dart

I want to make sure that the Voltage Regulator is grounded . I just added a flat braided ground strap from the back of the engine block to one of the master cylinder bolts . i was going to add another ground strap from the VR to another one of the master cylinder bolts ? Would that cause any problems , having both ground straps going to opposite sides of the master cylinder ?
You should have a ground wire or strap from the engine head (which is the ground from battery) to the fire wall (body). Clean all contacts and use dielectric grease at ends. I see no reason to set grounds to master cylinder.
