Reviving this thread
The initial question posted on this thread was about the correct length of the valve stem for the 1969 Rally wheel which was never actually answered. I'm finishing up the restoration of a set of YH rally wheels for my 1969 RS/Z project and am looking for the same valve stem length information. I've seen references to the Dill 418 stems (2") however would like to know what is the correct stem length and if possible a source for them?
