spark plug wires *stumped*

hey guys.. im lost.. i have an 01 w/ the 5.3L...i know how to do wires and plugs but ive never seen anything like this.. where the wire meet the plug there is a heat shield of some type does this heat shield come off w/ the plug wire. i would hate to pull and pull and break something.. thanks J

:yesnod:

is that a yes?? also any tricks on the passenger side last plug? can i get that from the top or do i have to go from under the truck?

got it all figured out.. it wasnt as bad as i thought it would be to get the last one (rear passenger) out..
