Any one know if the prop governor from vans has a spacer plate? I purchase one thinking it would fit my C4b5 but the studs are too short. Looks like there is a spacer plate on the gov. After hours at Hartzell so can't ask them.
Just went out and checked on mine (top cowl off). The governor has a 1/4" thick flange and what looks like a 3/8" spacer. I don't recall the spacer separate , it may be secured to the flange. All measurements are approximate.
