Where are 1967 Dart ground connections located?

I trying to check to make sure all the main grounds are installed after the resto. I found the one missing from the block to the firewall and replaced it. Made the tach act strangely when it was missing. The battery ground is connected to the block. These two I remember but I read there is another from the block to the frame? If so where is this located?

Not factory. Battery grounded to block. Jumper from block to firewall. It would not hurt to upgrade this in size
