Custom 3D designed (using CAD software) and printed (using PLA plastic filament) muscle body rebuild kits for 1975 GI Joe Adventure Team muscle body figures sold in the United States.  PLA is a plastic filament that is durable, and bends as shown in the last picture.  There are 4 versions (upper body, lower body and upper body and lower body with snap-on elbow and ankle joints which allow you to retain the original elbow and ankle rivets) and colors (Caucasian and African American) available.  NOTE: The snap-on joints work best if the original rivet is in good condition and unbent.  If the original rivet is bent, consider using my other non-snap-on kits that include a new rivet.  The upper body kit will replace the elbow, shoulder and neck joints.  The lower body kit replaces the ankle, knee and hip/waist rubber joints. 

For the lower body kits, you must choose either the narrow ankle (2.9 mm wide) or wide ankle (3.8 mm wide) version.  See 2nd picture in the listing of the feet to help you determine which version you have.  The foot on the right in the picture is the narrow type and the foot on the left is the wide type.  The narrow type typically has 2 notches right above the rivet holes.  Please be sure to select the correct type for your figure.
