Assuming it's imperial, the thread pitch of mine is 0.09 inches, The width of the cap excluding thread is 1.518 inches, including thread is 1.612 inches. All measured with a vernier. So depth of thread is 0.047 inches.
I am guessing you are at work all week, so not near your own car. If I can find my old standard landrover cap, would you like me to post it to you at work?
