I don't remember exactly what I did on a step by step basis, but I do seem to remember the little brad that holds it in place is rather soft Aluminum. I either just yanked the spring off and then squeezed down the brad's "petals" with needle nose pliers to remove it or did that in reverse order.
Installing the new spring and brad was about as simple. Once in place, the soft brad was easy to peen. Best I recall, I did that with a brass punch and small brass hammer. It "squashed" out flat pretty easily. The replacement spring and brad have been there through several thousand rounds since and it hasn't loosened a bit.
The CHP removed them from their older 4006's some years ago, and they ordered their new 4006TSW's without them.
The original TPS was a somewhat stiffer design that had 2 unconnected prongs on top. The revised design is less firmly tensioned, and is of a different style/design, connected across the top.
There's a seldom seen bright shiny "stainless" version that was developed and made for the fed's 10mm's. This TPS doesn't even have a part number (last I heard), and it's apparently not well known even within the factory. (Vaguely waved hand, and murmuring about these not being the 'droids you're looking for ... )
