Sorry, I always forget to add that. And my car is a 1984 300D. I'm not sure about the size belt, and I'm not near the car right now. I will say this, last I messed with the car, I was actually able to get the belts around the stock pulley, but that was with the alternator pushed all the way up in the bracket, crooked, and with the bottom of the alternator completely out of the bracket. Something tells me even though I got the belt on, I wont be able to get it straightened out and mounted with the stock pulley.
