Modifying the trigger housing:
This step is pretty simple. Since the Tank's action release is a LOT wider than the normal one, it won't fit in the slot in the trigger guard.
Grab your dremel and a cut-off wheel...
...and cut at both ends of the slot...
Since my trigger guard was of the plastic variety, it took about 15 seconds with the cut-off wheel to remove what needed to be removed. If your trigger guard is metal, it'll probably take a little longer, but the operation is the same. Clean-up the edges with a file and, if you have a metal trigger guard you can paint (or otherwise re-blacken) the exposed metal before putting everything back together.
Reassembly:
Clean all the metal and plastic shavings off of the trigger group and housing before you start to reassemble!
Putting it all back together is pretty easy. Just follow the disassembly instructions in reverse using your new hammer pin. Make sure the bent wire spring is UNDER the action release tab, and that the same tab captures the hammer spring and plunger. It really helps to have three hands when you're putting it back together.
Once it is all back together you'll need to stake the new hammer pin. I used a small flat-head screwdriver and a hammer to stake mine in three places. The following picture is blurry, but you get the idea.
