DIY: Berk Technology HFC Install

Quick update,

Finally got the two demon bolts off.

The bolt that was rounded off, tried extractor tool on it, extractor tool rounded off instead of grabbing bolt. Then tried to tap on a smaller diameter socket, no dice, so we ended up cutting the head off and grinding at the bolt for about 3 hours worth of grinding and checking and grinding and it was a joy when if finally came free.

The other demon bolt, added a universal joint to get past the steering column with 1/2 inch extensions and the baby snapped clean off. I was so happy I almost cried. No exaggeration.

The O2 sensor that didn't come out easy? Seemed to be cross threaded from the factory, there was a giant bubble of sorts connecting 3 rows of the threads. After not being able to find a dye big enough, we took a file to the bubble in the threads and made it fit well enough to screw into Berk HFC's and let it be.

Thank you to everybody who helped and made suggestings.
