Default speedometer gearing

The rear axle in my 33 has "11 - 39" stamped on the flange - a ratio of 3.54 to 1. I replaced the axle many years ago and I think the original was 4.11. (I wonder what the heck I did with that unit? Lost in the shuffle I guess).
My speedometer "turtle" has 18 teeth which I think is not right - it's probably the one from the 4.11 axle. It looks to me like I would need about 21 teeth to get it right.
I've never seen these things advertised as being available - actually it seems like it would be hard to get that large a gear in that turtle anyway.
Any ideas would be appreciated.
