Not quite done it as yet but I have bought this:
A metal shifter bracket off a TT. Once it has been tidied up and bushed with a 42 Draft Designs kit it'll be replacing the plastic and rubber existing parts. Not sure how much difference it'll make but you have got to be in it to win it...
Now the part has been cleaned and the new bushes are on order
Can anyone suggest a satin black paint for the bracket which I'm assuming must be galvanised as Mr Google suggests it to be a pita and for one small job I don't want to be spending loads (especially as once fitted it won't be seen again).
