I am rebuilding a 1973 (built) Plus 8 and have a small (literally!) problem with the little screws that hold the sender to the soldered-on fixing ring. I have been unable to find any screws that fit the threads in the ring. Does anyone know what threads they are? Thank you.
Ah, thank you Arwyn. Amongst all my collection of odd screws, I didn't have a 3BA to try - I had 2, 3.5 (electrical wall boxes) and 4, but none fitted. Off to eBay, then. Thanks again Francis
