well after a tt swap, i bent my NA prop to clear the driverside ic piping. the TT prop has a large curved spot to clear the pipes. My bent NA one works, but it doesnt look as nice as a factory bent tt one (it was bent with a vise shortly after the swap). Basically, its not a big deal, but if the price is right, id like to have a OEM one. Please send info to my email - tom@nismo.org.
