Also, I have a 5.0 in my truck and I needed to change my passenger side (which just so happens to be the tightest spot) and to make it alot easier, I took out the fender well and i got right in front of it! Saved alot of scrapes! Only downside is you have to unhook whatever is mounted on the fender well, but it usually is worth it.
