The prop is an 86 inch long with a 46 deg blade. Checked ground clearance and have about 10 inches with the aircraft setting on the dolly. Installed the prop using the hub plate provided and two 3/8 by 4 inch by 24 fine treaded bolts. Tighten the prop bolts to draw the prop onto the hub. It fit fairly tight. The 4 inch bolts appear to be the correct length with 5/16 inch extension beyond the back of the hub. This will support the installation of a self locking nut. After verifying the fit, removed the two bolts and checked the cover plate. The prop was sung to the hub and not removable with out a puller. Rotated the prop through a couple of revolutions and reinstalled the prop plate.
