Went through my picture again (now that I understand the question
Could not find a clear picture of a small block NJ 67 car so I looked through the (previous and following years to see if I could find a pattern that the workers might be following.
ON the few examples I could make out the details on I found that only the front bolt of the passenger side motor mount had a cable bracket and all were curled downward on the 66 and 68 examples as shown in the picture below. This is a 68 NJ examples only a bracket at the purple arrow and none at the red arrow/bolt
I would choose, unless something more concrete comes along, to copy this pattern.
Hope this helps in some way
