I have done this a few times recently in a change to carbon bowls that eventually had to be returned for a modification. As stated above, the spade connectors can be removed from the bulb connecting plug with the aid of a small screwdriver to release the plastic securing strip. However, mine are "L" shaped and too wide to pass back through the hollow mounting bolt. I had to use a pair of pliers to carefully fold the spade connectors over so that they would pass through the hole.
I am just about to fit the new carbon bowls again ... and it's freezing!
