Old heads

Posted in Custom Workstation

Hello Fellow Customizers, I have a question for you. I am attempting to make a custom using the head of an older figure from the late 80s. I was able to pop it off but then had to trim the neck to make it fit a current DC Classics/Marvel Legends neck peg. My question is what is the best way to secure it to the peg and still retain some articulation? I have seen some of you use the original TMNT and He-Man heads for current customs and wondered just how you do it and what needs to be done to the head since most of the figures from that time have hollow soft rubber heads? Thanks in advance for the help!
