The rocking ball lever/selector arm is pressed onto the pivot pin, 67 3136. the front end is threaded to be drawn out, accessed by removing the gear lever shaft bush. Alteration of this pin is simply not an option, (it has to be a plain shaft for assembly) but the provision to move this closer to the camplate is an attractive idea, but a non starter however it is considered.
Same applies to the claw pivot, 67 3133, but welding up and redrilling more towards the camplate is another option. Simply a change of the selector arm may achieve the intended result if there is variation in this assembly.
For finding hidden dimensions as in such cases as this I resort to good old body filler and a dab of grease to stop it sticking. At least some distances are retained, unlike the old standy of BluTack or Plasticine.
Swarfy.
