I'm working on installation of the spinner on my second hand Model IV 582 kit. The aluminimum spinner (GNC GA 3 blade wood prop), came with a backing or spacer plate. I'm thinking that the spacer plate fits between the prop flange and rear blukhead of the spinner. Is this correct? Also, what is the correct bolt size for mounting the prop assembly to the prop flange? Lastly, do I use bolts with the heads drilled for saftey wire facing foward and nylocs? Appreciate any guidance from the group. I have some missing assembly instructions.
