Dear David!
Thanks for your help. Everything here in SA is closed down, but I can get a drawing from CAV in a week or so, as well as information how deep Wheelcraft/WAW in Pretoria (Vintage) drills the wheels.
I am afraid, that the wheel stud is too long to accommodate a machined nut with hex head and not bottom out when tightened (or the nut now too long to sit inside the wheel)
The CAV GT40 studs could be shorter in the first place, because they are made up.
Possibly the stud diameter of 3/4" allows for a 1/2" thread and a 5/8" hex? That can be checked in CAD quickly.
Cutting the existing studs is possible, but a pain. Expect to wear out one speed grinder disk per wheel (5 studs). And now they are too short in case someone wants to fit 5-lug rims...
Nevermind restoring the thread.
I get the needed information soon and with the help of the forum we can find a solution. Just now I don't have a car or wheel&adapters here to take measurements.
The original/Kirkham version cannot be used for the bolt-on adapter unless we press out the stud, which is not manageable at home. And then we need enough clearance to add a nut to hold the (3/4") stud behind the hub.
Rick did extensive research to make his version work and surely can assist more than me right now.
