I've been working through a manual conversion I promised to undertake and I'm having difficulty with the M47 on my bench. 5th gear change is just not right. Odd wear in the slider that is making gear change hard, and I just can't find the fault by measurement or eyesight.

Does anyone have an M47 they are willing to sell, either complete or a parts box with 5th gear intact. Otherwise

I will end up breaking a functioning 88 factory manual wagon just for the box, which would be a pity, as they were never common.

Someone has evidently been in the gearbox before me, but the main gear set is still in great condition.
