The car is up on jack stands, not a lift; that makes it difficult to get much leverage, and I can't get my trusty cast-iron gas pipe under there.
The shop manual shows a special tool that bolts onto the flange, with a tang that reaches down the side of the diff, keeping components from turning. Of course the manual also shows this being done with the axle out of the car.
I installed the camshafts tonight, and measured the clearances with the new shims. The intake spacing is spot on at .4mm at each follower. On the exhaust side, I have two followers measuring .02mm too narrow (.43mm instead of .45). I'll order a couple more shims, and will likely be spot on there as well.
