I love the 67, very funky and nice sound.
You could try popping to a model shop and grabbing a bag of assorted cogs, failing that you may find a dead 67 CD somewhere.
It uses the philips CDM9/44 transport of which there were thousands made so it may be a case of finding a dead player that utilises that transport and doing a bit of surgery.
