Have you ever been at the junkyard and came across a rusty bolt that you could not remove. I have, and it's usually one of the last bolts that are holding on my desired part. Nothing is more frustrating!
Well don't worry, there is always a little junkyard penetrating oil laying around.
A guy at Pick-n-Pull taught me this trick. Brake fluid makes an excellent penetrating oil when all else fails.
Just cut you a piece of small vacuum line about 8 - 10 inches long. Take the cap off the master cylinder for the brakes. Dip one end of your vacuum line down into the master cylinder, and then plug the other in with your finger. Now you have a some penetrating oil for that stubborn fastener. It really does work wonders.
