I know this is an old thread, but with a new season, I am readdressing this. If there isn't another rear brake pedal plunger bolt that is available, I'm thinking of just ordering a 2nd one, and taking it to a machine shop to shorten the threaded end 1/8" and then extend the threads 1/8" farther up the shaft. I don't want to shorten the plunger side that is rounded as it is also plated against rust and corrosion. Any input from anyone who has done this or something similar?
