I don't see how you could possibly bore out an early upright from 90 mm 
to 100 mm to accomodate the larger outer bearing.

Here's a photo of early uprights, and I don't see how you could shave 5 
mm off on the radius, without compromising the integrity of the upright.

and here is a photo of one of my GT5 uprights:

The wall thickness is about the same for the two uprights, despite the 
later one having a larger diameter bearing.

The inner bearing is the same diameter on the early and late uprights, 
but the later bearing is a roller bearing that is 5 mm wider than the 
early ball bearing.

One other thing that indicates that the later uprights are beefier is 
that the bolts for the U-joint in the yoke can't be removed on later 
cars without first removing the yoke from the stub axle, and that is 
apparently possible on early cars.
