No idea where you can get such a gear. You could try to make one.

That's the hard and expensive way.

The smart way is to use a 63 tooth gear which is much cheaper to get,
I believe.

I worked out the arithmetic for use of such a gear some years ago and,
while the conversion is not exact, it is so close that the inaccuracy
would get lost in the accumulated tolerances of the lead screw and
gear train.

If you are interested in pursuing this let me know and I will dig out
my scribbles.
