Michael, I've had a damper rebuilt by Dale Manufacturing (ford 170 six) & he did a great job, though I haven't had the chance to use the damper yet. He usually has a good turn-around (about 3-4 days). I actually met the guy when I was in Salem OR, he makes a jig for each engine damper he rebuilds. Has a great little machine shop & is a nice guy to boot. Take care,
Edwin
