Just mount it into the swingarm and see if it is nicely centered Mick.
Thats what I did with a PE I restored once - It wasnt quite centered so I loosened one side half turn on each nipple, then tightened the other half turn...

I kept doing that until it was spot on.

Does that help?

Hi Mick, sorry but been away & just got back home to check the rims for you. Assuming that I have measured what you want & how you want correctly (see pic below), then the meaurements are:

Front 25mm & rear 35mm. Thats measuring to the inside edge of the rim
