I know that if you have a "no stop" external steering system (the one probably 99% of all W123s have) you can twist the front wheels a long way round if you have the steering box disconnected. (Wheels up in the air or on slip plates helps...)

I assume a system with external stops on the "steering arms or on the frame cross member" would involve obvious rubber stops and extra welded on parts / big lumps on castings on the bits that move.

I assume that these special steering arms are no longer available and as common as rocking horse ****

If you can't work this out yourself you might want to try

1) Posting up pictures of the steering arms you have - I'm sure most of us here will be able to say "yep seen that before" or "holy crap that'll be worth a lot on ebay"

2) Ringing up the Mercedes classic centre and seeing if they can help

3) A practical trial fit / assembly. Front wheels on slip plates - no power steering - steer to full lock one way look for parts hitting other parts - steer to full lock the other way and look for parts hitting other parts
