Rich, There's plenty of room for cake mate.
Paul, The flaps will be staying but i will do the spacers when i fit the H&R's, my new wheels are a different offset so don't want to go to wide with the hub spacers.
Glenn, Yes all new surround then a little 'trimming' of the plastic behind.
Andy, Yes you can get them from Ford, I just took the reg of an early one that has them standard and gave this to the parts man as they don't like having to do any proper work.
