engine mount rubber replacement 318 Dart NEW QUESTION

I understand now. I was confused because Ironracer said he got the wrong part. Even with the correct replacement polyurethane you still have to drill out or burn out the original rubber. Thanks for the replies.
The wrong part I was referring referring to was a bushing kit from Energy Suspension. One of the bushings was Wrong. They sent me a duplicate of the other side, but it showed up after I milled the other one down to fit. Sorry for the confusion... sometimes it follows me... lol
