I'll give you a bump to the top with a few things to explore. Remember, Google is your friend, and there is a search feature at the top of this page. You as a member should avail yourself of both benefits. Capisci?
I believe the 2006 cut off you are referencing to is related to the Lee Lever Prime system which is associated with the placement of a small lever which fits under the shell holder in the slot seen directly in front of your ram.
The L shaped lever drops in that slot, and actuates back and forth depending on ram stroke. At the top of the stroke the L is out all the way, wait for you to lever in a primer at the very top of the stroke. On the downward travel, the L moves in under the shell holder and positions under the primer pocket and presses the primer in the case.
My guess is that if it is your press in the picture, you will be good to go, as it has the slot for the L lever.
Remember your safety is your responsibility.
See the following picture from Lee:

This video will make it all clear.
