Hello, I think I need some help here. My cluster went out in my 300e, I got one on e-bay from a wrecking company....I think Im going to run into a problem tho. The new cluster is out of a 91 300E and as I said mine is an 86 300E. Are the gears different? Will the Speedometer be off? If so, how do I Fix it?

I would like to say thank you to everyone, I have a better understanding of my great little pain in the butt car, and i have enjoyed reading the posts.
