Actually, an early world class trany will still have the mechanical drive speedo. The later ones have the electronic drive for the speedo and will not work with a mechanical speedo like the Model A.
The plastic driven gear in a T5 is common in most early GM tranys...including automatics. There are almost an infinite number of different tooth configurations available to dial in the accuracy of your speedo. I have a WC T5 in my MGB with a Rover aluminum V8 and Camaro T5 and the original MBG speedometer is dead nuts on with a GPS.
You will probably need a custom speedometer cable with the Model A end on the speedo side and the Chevy end on the trans side. Any speedo shop can make one up cheaply.
