As no supplier seems to have 1/4 Whitworth(no surprise) would anyone know what I could get away with in terms of drilling and tapping for 1/4 Whitworth? I was thinking No. 10 would still leave enough meat in the nut. These are only going to be used at the rear of the side panels so won't carry much of a load. I'll likely use the solid ones rather than the caged ones and attach with solid rivets.

1/4-20 UNC? ...should do it in place of 1/4 BSW. Without looking it up I do not recall the across flats dimensions of the nuts, but the threads are VERY similar...
