I know some people don't like it when ancient threads are revived, but I just did this fix on my car. I didn't know how to remove the under dash panel (should have looked it up here), so I broke a couple small plastic tabs. What took the longest to get this done was getting the boot to seal properly in the firewall. There's a little groove in the seal that you have to get the firewall metal to set into, if that makes sense. Maybe my fingers are weak from not doing much car maintenance/repair lately. I made a couple quick videos showing the completed job.
