Ok as requested earlier more details on the lower arm swap - with pictures

Note: B&P - boil and pop method involves warming water, hot - does not need to be literally boiling. I use regular coffee mug full in standard home microwave for 2min. Dip part to soften in the water for up to 30 seconds or so. Plastic will soften and allow removal of pins, wrists, elbow, ankles etc.

Step 1 - Using B&P soften elbow joint of deluxe figure. Remove elbow pin. I use blunt back end of drill bit, piece of small metal rod to push pin through, or sometimes screw-driver feature on small swiss-army knife to pry sides of elbow off ends of pin.

Step 2 - With arm/elbow joint still warm from B&P (or rewarm), remove pin and lower arm completely.

Step 3. - (GI Joe parts pictured, Cap A figs same style contruction), Using B&P soften entire arm/upper arm on standard figure and remove lower arm and elbow joint from upper arm.

Step 4. - The lower arms on these figures are made of a softer, more flexible plastic that is molded around the elbow/lower arm swivel joint piece which is previously cast out of harder plastic. So there is an internal 'pin' of softer material molded through the elbow/lower arm swivel joint. Using an exacto or similar, slide knife down 1 side of hard plastic elbow joint piece and cut through internal pin.

Step 5. - Using B&P soften lower arm and remove hard plastic elbow/lower arm swivel joint from single-carded figs lower arm

Step 6A. - NOT PICTURED - you will need to ream out the hole in the standard figure'ss elbow joint/lower arm swivel loop. You could use the exacto knife from before, or small drill bits, or small file, or I use a dremel with small diamond grit bit. You don't need to enlarge the hole very much, just enough for the elbow-pin from the deluxe figure to fit through. Use the pin to check fit as you remove material.

Step 6B. - As pictured slip hard plastic elbow joint/lower arm swivel loop into slot in deluxe figures lower arm. Soften lower arm with B&P and reinsert pin.

Step 7. - NOT PICTURED - Soften upper arm of standard figure and reinsert barb from elbow/lower arm swivel joint now pinned into the wrist-articulated lower arm from deluxe figure.
