iL (Industrias Lorenzo) released a brand new alternative shaft for the Eurojoystick lever series with 6 mm threading for any standard top to that spec.
This is a brand new shaft available from iL for their Eurojoystick series. Rather than the standard plastic coated shaft with fused bat top, you can now use any ball or bat top with 6 mm threading. It's also possible to use 10 mm theraded tops as long as you include a 6 mm to 10 mm thread adapter.
