Shooting flash with the FSU cams

Obviously the accessory shoe on most FSU`s was meant more for using a finder than a flash since it gets in the way of my forehead and all but prevents easy focussing so I figure a bracket would work better.
The problem is the larger (3/8" X ?)than currently used 1/4" X 20" (US)screw size needed.
Could someone please tell me how to get around this?
Is there an adapter available and or what is the exact size of that camera thread ?
Thanks for the help.
John

That`s the one. Thank you Vlad. I ordered a few of them just to have on hand.
