[Healeys] Thumbscrew threads

[Bob Spidell]

Anyone know the size and thread of the studs on the back of Smiths 
speedos, tachs, etc. (the ones that hold the clamps to the backside of 
the panel)?  We have--ahem--'aftermarket' screws intalled by a PO on our 
BN2's speedo, and I'd like to get back closer to original; I have new 
thumbscrews but they don't fit any screws in my inventory (looks like 
size 8 but the thread is not 32tpi--24tpi maybe?).

TIA,
Bob
