I've got a Canon FD 55mm f/1.2 that has some fungus behind the rear element. The rear element looks like it might just screw out. Although it looks to be glued in place. Any idea if I'm on the right track? Any suggestions for a solvent for the glue?

Thanks for the link. I'm not sure I will be able to remove it though. I think it may be permanently glued. It's the rear most element pictured here:

I don't think it screws out and from looking at those disassembly pictures I don't think it's accessible from the front.
