Hi all,

A PO cross threaded the threads the chrome nut screws onto that secures the hood release cable to the bracket just under the dash on my 1970 car. What MM size is the chrome nut and its pitch? I want to chase the threads with a die to fix the threads. I measure the pitch as 1 and the diameter of the threads as 9.5 MM. I can't use the nut to figure this out because I damaged it before I figured out what the real problem was. I would think the 9.5 MM measurement means the nut is a 10 MM nut however the tap and dies set I have does not have a 10 MM nut with a pitch of 1, it only has a 10 MM with a pitch of 1.25. I probably am the only Z car owner in history who has a car with this problem.

Turns out the threads were stripped on the cable mount, not the chrome nut. The threads are 10 MM with a pitch of 1, bought a metric nut to test.
