Backhoe 2003 4310 with a 47 Backhoe L pins not aligning?

[erniecumbra]

I unattached my backhoe a few years ago, the LPins are just off a 1/2 or so.
The rockerarm is attached correctly. They is a adjuster nut on the left side, I can't remember if this was for that.
My local dealer said to use the out rigger and bucket to align it properly.

My question is, what is this adjustment bolt for? And any other suggestions?

The other picture is the LPin alignment I currently have. Thanks!
