After mounting the engine I cleaned up and repainted the flywheel. However, the paint came out to light so I will repaint it later with a darker shade. For now, I put the flywheel in place and then mounted the prop extention temporarily. The prop spacer from SABER is a piece of fine art. They are out here in the DFW area, so I got it very fast. I also bought my prop bolts from them. This is the "delux" unit that uses two sets of bolts, one set to attach the spacer to the crankshaft flange and a second set to attach the prop to the spacer. the basic unit uses long bolts that pass through the spacer into the flange.
