David Dodge,

Could you provide some more description on your fix - like what parts, where is it located, etc. I've had a flaky tach on my '83 300D since I bought it. Some days it works, some days not. It feaks-out when I honk the horn or go over a large bump. I'm thinking I have a mix of mechanical and electrical issues, but I'd like to make some progress on this.

Thanks!
