Mikebro,
All the treads on the Solex carbs are Metric .
The banjo bolt thread is 12mm x 1.25 pitch
It is important to drill the old hole out to the correct size ,square in both directions , then tap the hole with the Helicoil kit tap and finally face the outside edge where the fibre washer makes contact .
Then fit the Helicoil .
Unless all this machining is done in line you will have problems with leaks at the fibre washers .
I suggest all three carby tops have the same treatment .
If you don't have some milling or drilling equipment take them to a engineer to have the job done .
Good luck with the restoration.
