Thanks

Thanks, Simon. I suspected as much.
Presumably ok to machine the lip off the centre?

Does this look like a mix of parts on my '54 Square 4?
Should the clutch centre not have the lip, as it's got the friction material on the basket?
If so, is it ok just to machine the lip off?

Sorry if this is a daft question, I'm new to Ariel ownership.
Thanks, Neil
