Hey everyone!

I see my post was revived, so as a follow up...

I soaked both upper motor mount bolts with a corrosion spray (forget the name) for about 3-4 days before the job.
I jacked the car up and was able to get a 17mm socket on the bolt using a stubby ratchet from under the car. Now I don't know if the corrosion liquid did it's job or the bolt had loostened up from all the shaking the car was doing but it came off almost too easily. Once that was off, the rest of the job was a piece of cake.
