I just finished installing a 3.21 final drive in the coach.

What is the capacity of the 3.21 final drive?

I checked the 67 Olds Toronado manual on the 3.21 and it states 4 1/2 pints
and I thought that I had read somewhere out here on the forum that the
3.21 final drive should not be filled to the hole in the cover but rather
the fluid should be an inch or two below the hole.

So I add two quarts of gear lube and just as I am finishing up the second quart
it starts running out the hole.

Am I missing something? or is the manual a misprint? The drive was completely empty
when I installed it.
