Nope. They wouldn't remove the v6 for the ecoboost. They need something to set the absolute base model. It would be cool if they had an Ecoboost v6, but then it wouldn't really be an "eco" car. It would just be a faster v6, still just as heavy on fuel!!
Good choice. You might not know this, but when you pull the spring out, the clutch rubs against the wall. Eventually it breaks through and is stuck. The spring is there to stop that and push it back. The clutch spring is one of the most important parts of the clutch.
I'm in Australia. We drive on Left side of the road with driver on right. I don't have a rhd mustang as of yet! My 67 is LHD so it is harder to drive for me!
