For a spinner I ordered a [link=http://www.tru-turn.com]Tru-Turn[/link] (
http://www.tru-turn.com) 2 1/4" spinner with the cone cut to accomodate an APC 15x8E or 14x10E
The adapter used for this setup was the MP Jet 8mm prop adapter.
In the images below you can see the Tru-Turn spinner before installation and after and also the MP Jet prop adapter.
