My C9.25 CF has an interesting arrangement of screws. From memory the upper and lower body had one screw in the front (to mate rails top or bottom) and a choice of four holes at the rear (two always plugged). This allows one to set up for wide or thin rails.
As stated the Losmandy D rails mate really well and are very secure.
I do recall having to drive all over Sydney, eventually out to Parramatta to the third and largest specialty screw stockist I could find. The screws used where very unusual - American gun sight screws I was informed. They had a very unusual pitch and thread width (certainly not any normal metric or imperial screw). Normally I thought you just matched length and size - but oh no - I could match that, plus pitch 8 / 32, but the thread width was distinctly unusual.
Check closely on the screws you may need. If not included and of the right length you may have to search long and hard to find a stockist.
Oh and cut them to the right size - make sure a re-fitted screw won't hit the mirror when you move it in or out or you might be able to damage your main mirror! I cut mine to lenght by measuring them first, then you screw a bolt or two one and use these bolts to hold them firm in a vise; then use a hack saw to remove the excess length. Then you lightly file the ends, take them out of the vise and finally screw the bolt on and off twenty or thirty times until the end is smooth and it goes on and off with no roughness.
