550 Shifter Position

I've been unable to find a posting on aligning my 550 gear shifter. Mine sits a little north of the gated plate centerline. The position is not keeping me from making shifts, but I get a shifter to gate-plate metalic "collision" when I go between the vertical paths (ex: 2nd to 3rd or 4th to 5th).
I've looked through the online diagrams without finding an adjustment part. American car linkages I've adjusted have a threaded coupler so that the length of the shifter-to-trans throw-rods can be lengthened or shortened to center the shifter. Guidance is appreciated.

You are always very helpful with your F-Chat posting. I agree that the "F" coupler looks to be the only joint with potential threading. I don't have the diagram you posted from your 575 WSM in my 550 WSM. The cars are similar. Do you have a digital copy of the 575 WSM and will you share it with me? If so, send me a PM through CONVERSATIONS (to crburg4) and I'll provide my email address.

 

Thanks for responding. I've pulled the shifter plate, looked around and found nothing. No coins in the compartment to cover the next annual maintenance costs. The shifting is full-range without binding and I've put 6K miles on the car this past year, so I suspect that if there was an obstruction it would have produced some negative results by now. I'm the 4th owner and I did find find a maintenance note indicating that the shifter position has been aligned in the past.

 

Thanks for your response. Your information tends to point to the "F" coupler in the diagram provided by Tazandjan above.

 

Thanks - a good warning message. Fortunately, the shifter plate is not limiting the shifting in any direction. It's bothering me that I get a metallic "twang" from hitting the downward tooth between 1 & 3 when I slide from 2nd to 3rd. The adjustment is out just enough so that the shifter hits the top teeth when the shifter is moved side-ways, but doesn't touch the bottom teeth.
