Re: 36 Pickup Turtle
The tire circumference changed. Housings might interchange but each one is a bit different due to the circumference of the gears and different shafts. Speedo cable connections are different shape on the model A ones depending on year of manufacture. They are numbered for the size of the gear. You need to find the number housing you need according to the chart in the green bible. I'm pretty sure that new gears are available.

Re: 36 Pickup Turtle
That's the year, but that has nothing to do with the ratio. What you need to know is part number of the housing and the number of gear teeth it has. It will depend on the original rear axle ratio and tire size (assuming everything is factory original). The base number is 17270.
