There are so many different screws in the boutique...
So please: Who knows for sure the number of the two Phillips screws? (And maybe the measures? - I want to tinker around with different brackets and tailpieces...)
These screws locate the original die-casting bracket for the R-tailpiece.
The parts diagram at RIC's site just tells the number of the strap bolt that goes through the bracket, too.
THX by now!

IIRC, without taking my guitar apart to find out, this should be what you are looking for:

Same as pickguard screws.

The information is in the schematic here:
http://www.rickenbacker.com/pdfs/gtailpiece.pdf
which indicates that the part number for the two bracket mounting screws is #5204:

Jeff's suggested part #5202 is close, but the correct one is this one:

So, what's 2 between part numbers?
Go with Gary's part number; I did not see that drawing. I saw that part in the boutique and without removing the screws from my strung up to tension 330, I made my best guess, just like Spock would, except that Spock is never wrong!

Thank You, gentlemen!
(The R-piece diagram i did not find.)
And now can look in a local hardware store for flathead screws with the same thread...

Additional question:
The screw is described as "SCREW TAP 4 x 1/2 OV PH"
1/2 surely means 0,5inch (metric: 1,27cm), right?
But what means the "4"?
I need the diameter of these screws in inch or centimeter/ millimeter because I do not want to enlarge the existing holes when using metric flathead screws at this place instead.

Yes, you are right about the length being 1/2 inch. The "4" refers to a screw "gauge" which is an old fashioned unit of measure, screws smaller than 1/4 inch use "numbered" sizes from "0000" to "14." These sizes (as well as the old English inch/foot/yard types of measurements

) are still in use in the U.S. where they seem to have given up on converting to metric sometime in the mid 1970s (so now we have cars and such with BOTH metric and inch sizes

).
Anyway, it's not closely related to anything like metric sizes, so you will probably have to find a source for U.S. screw sizes. Here's a chart with info on wood screw sizes:

Also, the "OV" refers to "Oval" head screw. This is like a flat head countersunk screw but the exposed portion is domed/rounded for a nicer appearance. I'm not sure what the "PH" means. This often refers to "Pan Head" which is a normal, non countersunk head with a domed surface, which this screw is not...

I think you'll find that both an M2.2 or M2.9 x 13 mm sheet metal screw will be a close replacement. Oval head screws come in varying head sizes, so you'll have to check that: optimal is about 5.4 mm. Stainless steel would be your best choice for screws at retail, as chrome can be hard to come by.
