Wow the pin thing sounds like a pain, yet I still look forward to getting a W123. Sorry I have no pics I didnt have a camera and I forgot my phone. Anyway the end of the crank is a little taperred and the balancer is completely wallowed out and the key is gone. The crank is a kind of ugly but I am confident that it will hold a key and that there is enough meat toward the back of the snub to hold a new balancer true. My major problem now is that I need a balancer. Does any body know if an OM603 Balancer would fit? Or if there is anywhere I could get a new one that isnt the stealership? I am desperate, this car is my primary sorce of transportation and I need it back on the road quick.
