Ghosthead Maverick 1983 picked up a Kenner The Real Ghostbusters Proton Pack and decided to customize it more like its big brother movie version as much as possible. I only recently saw he’s working on this project by his thread on Ghostbusters Fans.
This project is continuing with the Nutrona Wand customization and possibly lights for the pack. To follow the build from the beginning with build pics, check out that message board thread.
