A few weeks ago, I received a message on fb regarding a 3d printable tool that could help with taking apart the earlier style GS forks.
The nice fella that messaged me designed one and requested I post it here for anyone interested.

There is a description/summary under the pictures in the above link. If anyone has any questions about it, I can get in touch with the designer and ask.
