Still trying to get the set screw out - need help

[Roadrunner]

I have been trying to get the set screw out on the bottom of the ski arm to get the struts off. I broke 3 very good allens and I just can't seem to budge the set screw. I have it soaked in oil but nothing yet. Any other ideas besides drilling it out?
Thanks again,
Doug

PB blaster...I'd blast it in the morning, blast it in the evening for a few days. They can be a bitch...Blue

Have you tried Aerokroil,
it's the only stuff we've tried (that worked) here at the shop to help remove stubborn spark plugs on the newer Ford 5.4L 3V engines.

You can always try an impact driver with a good bit, any mechanic friends might have one! Good Luck!!
