[6pack] removing rear drums - stuck screw

[Bob Labuz]

Sloane,

In addition to Larrys suggestions below, try some wax after heating the 
area red-hot. Apply, re-heat etc. That trick worked for me when removing 
a rusted stud on an exhaust manifold when penetrating oil did not do the 
trick.

Another trick is to use a butterfly wrench with a screwdriver 
attachment. Set it on low torque first and see if the impacts can make a 
difference. But, as you might guess, you have to really hold the wrench 
tight so it doesnt strip the slot.

Also, when you re-assemble, make sure you use anti-seize on the threads.
