Well I don't know if this is any help but here goes:
On the left of the playfield, the hex posts should be like in the picture with the playfield: medium, medium, long, short.
Side by side they look like the picture with just hex posts
For some reason when I did my teardown I took a few pictures which show some of the lengths, but I don't know which hex posts they are: the ones on the left or the ones that support the right ramp. (It was a while ago now)
I hope this helps
