Worm gears for speedo 442 1987

[Deleted member 33916]

Good afternoon all! The odometer in my 442 hasnt worked in yrs. I took the speedo apart the other evening and found the problem aside from it being dry. The 2nd and 3rd worm gears bound up and the 2nd wore grooves in the 3rd enough that it wont spin.
My question is does anyone make these or have spare parts? Ive checked all speedo rebuild and nothing. Any leads would be appreciated.
Thanks.
