Rear brake banjo bolt/61 Bugeye

[61frogeye]

I believe this bolt head is Whitworth, does anyone know the size of wrench that fits it properly. It is a thin head and made of brass so it is easy to ruin.
Thanks

I rebuilt my brakes recently, I'm pretty sure I used a metric wrench on that one. I know nothing on these cars should be metric, but metric wrenches often fill the gaps between SAE sizes if you don't have whitworth wrenches.

Here is a conversion chart I found somewhere on the internet.

That chart is a keeper! I found that the banjo bolt head is larger than 9/16 and smaller than 5/8 so I will try a borrowed 15mm box end.

15mm worked great. Thanks again David.
