Are you jacking the car up a bit? I put mine up on the T-bars and remove the rear wheels. Remove the air cleaner housing, and heater tube on top, and I seem to have all the room I need. I use both the backside (to adjust) and normal (to verify) methods, and it takes only a few hours. For the adjustment, I removed the two feeler gauges that I need (.0025 & .0030) from the tool they come on, and fit the .0025 into place with the lock nut loose, and tighten the adjuster down onto it. Then I tighten the lock nut and pull on the feeler blade to remove it. If I got it too tight, it won't come out. If it slides out with any resistance, I'm done. I really like this feature of the backside method.
