%!@$&!!! I broke two bolts off putting the water pump pulley back on.

I've used dozens of times and yes works amazingly well. I also use the method to install the from the back bolts that hold the rear wheel bearings on e53. You can turn the hub to align the bolt and a long flat blade will reach through to snug up each bolt then you need less than 1/4 turn to torque them and with two wobble extensions you can work around the CV joint without removing the axle or the suspension or the exhaust
