Help, no backlash on my Intermediate gear

Ok, here's the rundown. My 67S came with a 68S motor, so during my rebuild I picked up a 67S sandcast case and the proper intermediate shaft/gear. I'm using the crank from the 68 case and when I fit these together I get absolutely no backlash. Everything turns ok, but there's no play in those gears. Both intermediate shafts have "0" gears and this setup worked fine in the old mag case.

So the question is, how do you adjust backlash? The only way I see it is a different size gear...slightly smaller. Where does one find such an item and how do I know what size to get? The other question is, why did this configuration work in the mag case and not in the aluminum one, is the spacing between the shaft and crank bores slightly different?

Help...... Bill
