Dart driveshaft needed. Any info would help

understood. Thanks. Is there only one place to get that bushing? The guy charging 40$ or is it something that can be made pretty easily?

It can be made fairly easily, if you have a lathe. But if you figure time=money, it is not worth making just one, at the price I charge.
I have the bushings available. $20 includes shipping, in the US. Send a PM if interested.
