Proper 3500S accelerator shaft obtained from Wins, snazzyfied with some rattle can silver, installed in place of former automatic item and unnecessary bracketry – lovely jubbly! Much nicer angle at the replacement plastic coupling, no more unsightly redundant 'ear' for the automatic kickdown cable, less clutter. Thanks for that suggestion Harvey!
Now some photos of all the bits and pieces I got from all over the place to perform a manual gearbox transplant.
Which isn't working properly, though more on that when I find the problem and rectify it.
