Mike, I checked the local junkyard, but the 240D they had was a 1982, and they also had a 300D. But, like I said earlier, my stop lever is unique to a single year and model. And even if I could have found one, it probably wouldn't be in much better shape than the one that broke. For a critical part like this, I think it's worth spending a little more money.
