Check the way the 41 tube sits in its torque tube.
The 40 Ford had a solid shaft, and required a bearing inthe torque tube to locate it.
The 41 torque tube will bolt up to the 32 gearbox. I bolted a 40 ford to a model A, not al the bolts were the same, but sufficient were to enable the job. One had 4 bolts the other 6, but used the same ones.
the universals are the same from 28-48, so that base is covered.
Maybe a flathead site will give you the exact details.
Do you have any pics of your roadster? love to see ém
