Swapping out heads on figures is one of the more basic modifications out there, but occasionally there will be a figure with an overly short neck peg and nearly every head you try sits low and looks like it's attached at the shoulders. I recently decided to swap out the Marvel Infinite Thundra head on an extra Valkyrie but found that head sat too low on the neck. I performed the following mod to extend the neck peg and fix the problem.

tools and materials you will need: Xacto knife or razor blade, small drill bit, pliers, super glue, nylon machine screw and nylon washer (these should be sized according to the figure, most male figures will need a larger screw/washer combination, female figures smaller).

This neck extension mod obviously only applies to figures with soft plastic upper torso pieces, but, as stated, could be adapted to add length to arms and legs as well. Hopefully this tutorial proves useful to fellow customizers out there. Cheers.
