Without the actual specs I am not going to speculate on what it will or won't fit, but I believe the bolt on the 6.5 SAUM is the same as the WSMs. Likely too fat to fit in mainstream SA's.
If you go looking for a new guide, PMA Tool has a really nice setup. You may need to dig around on their site (or send an email) to make sure you get the correct rod insert for your particular cleaning rod.
