I have an old Meade 6" reflector that's at least 30 years old. During a move a while back, one of the screw/nut fasteners that holds the secondary mirror spider assembly to the tube snapped off (long story). The secondary mirror is now unstable, obviously. Here's a link to an image of the part I'm talking about:

And here's the scope itself for reference:

Is there any online supplier for these obscure parts? I tried my closest Meade dealer/service rep (in San Antonio) and they looked at me with a baffled look and suggested I try Home Depot. The Meade website was not much help, either, and my email queries have met with silence. Any suggestions (other than "Home Depot") would be greatly appreciated!
