There is a really cool nuts and bolts shop near where I work. I can take in any screw/nut/bolt/cap screw and they can always get me what I want - in various types of stainless, black, any length, any qty etc etc. These places are really handy and they have no issue selling you a single screw for 20 cents or whatever it is.
I'm going to remove the mounting foot on my 72FD soon and that's where I'll get a replacement screw from.
I replaced all the rusty screws on my Mak Newt with nice shiny stainless ones from this shop - it look great now and it only cost a couple of bucks.
IMHO the Megrez scopes look great - don't wreak it with a shonky job - looks **are** important guys!
