The paper will center the gear
and give you the .0032 mesh clearance on both sides. Give it a try, its free. Are the idler shafts going to sit square on the block? Just trying to utilize those existing Dogbones for some sort of square up support. ie remove small gear, swing them up 90 just outboard of the cam gear and use them with a hollow axle for a second mount point. May be overkill if the bearing base sits flush on the block and a grade 8 bolt will keep if from walking away from the gear? Just thinking about rigidity... or even deleting the small gear as it sits and use same hollow spacer axle as 2nd mount point, maybe a little cleaner.
