At first I thought it would be a BA thread, but I've just taken a screw out of my FPC and measured diameter and thread pitch. It is around 0.161 diameter x 32TPI. A 3 BA of that diameter is 34.84 TPI. So that would suggest either 8-32 UNC or even No.8 ANC. It could even be no.8 BSC, which is used for wheel spokes.
I suspect 8-32 UNC. However the screw I measured was a bit tatty, so after all that it could be No.3 BA
ANC threads are quite rare nowadays I suspect, but fairly similar to unified.

The offer is still there.
If you want one, no problem at all as i mostly work with villiers ignitions which use an entirely different baseplate screw.
Off the top of my head i have around 10 of these screws along with the ht retaining plate that the screw goes through, absolutely no use to me whatsoever.

Did you sort your screw Super st?
It seems to be a very weird thread, Wipac must do the same as Amal.
As by my measurements it's 4.1mm x 0.8mm pitch which is very close to 3/16 BSF you should be able to get the 3/16 on the web, but only buy 1 to try out as the major diameter seems a bit big.
