i am trying to replace the struts on my 87 lx, but i can not get the nuts on the top of the strut to budge. i have soaked the nuts with penetrating oil, no luck. i have tried my best to hold a large screwdriver in the shaft and turn the nut, but cannot keep the screwdriver tight. i have thought about getting a nut buster or cutting them off with my dremell. any help will be accepted with many thanks.
