Hi guys. Can someone tell me the correct thread size of the vacuum hose clamp in the top of a 35/36 roadster, phaeton windshield frame? There’s only 1 in a lhd car, 4 on our Rhd frames. Thanks Dan. Ps I’m assuming it’s 10-32, but not sure
 
Ok I managed to get some out of rusted original Aussie windshields I have and they both had these. Taking to town and see what I can find. But definitely a parallel thread not a sheet metal screw.

I'm nearly certain they are 8-32 machine screws.

Ok so I took a screw to a bolt shop and they are 6-32. Now to try find them in stainless slotted!

Sorry I misled you. The ol' memory is not what it once was.
I will look later today as I may have one or more for you. I owe you that :)
 
All good Kube. I have found an Aussie supplier that has got some in stock so I have bought the whole lot! Now to make the clamps in stainless.
 
Thanks Kube. My clamps turned out pretty nice. The screws still need to be replaced once they arrive.
