Yes I have the acorn on the lever jp, I thought there might be another for that part, and the mechanic agreed that there should be "something" there.The 'acorn' goes on the end of the gear lever. That part (selector peg?) should have a nylon cap on it, but rare and I think unobtainable. See if you can find something to go on the end that will just fit in the selector slot , or braze and file back till it fits.
