So there isn't a standard for the dimension from the mounting holes of a lunette ring to the back of the mount; the reason for that is different manufacturers have slightly different thickness tolerances and design styles - a Bulldog like part # BD1291020340 is a little different than the Titan # T1613700, for example.

I went out to the warehouse and measured the Curt pintle hook # C48006 for you. I have linked the measurements to this page for you to check out.
Dimensions of the lunette outer rings can differ from manufacturer to manufacturer. You will see from the diagram that with the ball in place there is only 2-1/4 inches of space between the ball and the pintle on the Curt # C48006. If your lunette ring will fit the space available and the 2-5/16 inch ball of the pintle then you can use it for... view full answer...
The Curt Lunette Ring with 5-Position Adjustable Channel - 3" Diameter - 12,000 lbs # C48640 is not rated for a vertical load or tongue weight capacity.

The hardware size to use with the Buyers Products Lunette Ring part # 337BDB125015W is 5/8 inch in size so if you went with a Grade 5 bolt it would need to be 170 ft lbs or 240 if Grade 8. In reality it's about what the hardware calls for and since this doesn't come with hardware the ring technically does not have a torque rating. view full answer...
