Coolant Leaking Problems of Mazda MAZDA3

There is a recall applicable to my vehicle which requires that engine mounts be stablilzed. It makes my car vibrate and the engine sounds loud while seated in the vehicle. I have taken my car to a couple of dealers and they say they don't have the required part. I was scared to drive my car. Because it was smoking from under the hood. I let it sit in my garage since 2008. I finally took it to a mechanic who told me that the engine had caused a hole in the coolant tank and it was leaking coolant. That's why it overheated. The car runs fine now, but needs to have the engine mount put in. What do I do now? in addition, my driver side window will not operate. I thought this was a fuse issue, but another Mazda 3 owner told me they have the same issue.
