3.9 Mag Distributor drive bushing

I have a 91 Dakota with a 3.9 Magnum engine. Quit running on me. I discovered that there was lots of play in the distributor rotor. Pulled the distributor and discovered that the distributor drive gear was chewed up. Pulled the dist gear and discovered that the bushing is bad. Two questions: 1) how do you remove the bushing? Can it be done through the distributor mounting hole? 2) What is the best source for finding a new distributor drive gear and bushing?

Thanks
