Have a TF Duke or DVD Duke, but you'd rather have V1 Duke with fixed arms? Yeah, me too.
Here's the "HOW TO" diagram:
For those of you who find it easier to just paint updated Duke arm elbows to match the upper arms they're attached to, if it works for you, then keep doing it. Here's a mod for the anal-retentive guys like me who want to keep as little paint as possible from messing up factory paint/plastic that is fine as-is.
Essentially, you take TF Duke, DVD Duke, or any of the updated Duke arms, pop the lower hand off the elbow, and then do the same for the old Duke arm that you want to fix.
Now here's where it may get a tad tricky... You want to take the old Duke arm, and with a sharp Xacto, simply chop off the flesh part at the edge of the sleeve. Then, cut off most of the hand, but leave the wrist attached to the peg. With a Dremel, or however you want to hollow out the elbow nub, you're going to want to make a pit big enough to fit the hand-stub into. Cut deep into the elbow so that the wrist piece will fit in snugly, and glue it in place. This should give you enough of a base to hold the mushroom-tipped plug in so that the arm can still swivel.
Here you'll see the cuts (and the scraps), and the amputated lower sleeve with the hole bored into it (for the new plug to fit in:

Done! New nubs for fixed Duke arms to fit onto:
Obviously, allow proper glue/dry time. But this way, you only end up chopping up the crappy arms that you never liked to begin with, and may save you painting hassle or from having to buy multi-pack figures (like the updated Breaker or Clutch) just to get ones with correct arms.
If TF Duke clogs pegs like I expect him to in the future, he's a great donor candidate. His arms also pop onto the Greenshirts without any cutting; the green matches perfectly. I've already fixed 1 greenshirt, and it looks fantastic.
