I think it was Rusty that indicated he was using a prop extension. Was this with Tracy's redrive?  If so, how does an extension work with the metal inserts that are in tracy's hub?
I think I need a 2-2.5" extension to make things fit easier.

Hi Bill.  The extension is bored out for the drive lugs.  I just test fit my new 4" prop extension yesterday, and it's a very tight precision fit.  Spruce carries these, and they're all special order items.  You have to tell them exactly what hub you have, what hub you want for the prop, bolt sizes for both, etc.  Mine was about $400, and weighs 6 lbs.  Price and weight will be reduced at shorter lengths. 
 
Cheers,
Rusty (back to the torture session, aka fiberglass)
