Just a note if anyone needs a prop hub so you don’t have to install your new prop to fit your engine cowl I will loan out the one I have if they pay shipping it is for the Ex3 363 hartzell trailblazer you will have to install your spinner backing plate on the hub to do the fit up. my used hub has bolts and spacers.call Gordon at 616-291-3969 or email me at g2eng00@yahoo.com. Buy the way Dave you have been a big help to all builders out there and thanks for all your help with this build threads.you have done a great job with this.
