I've been doing some checking and from what I can gather, if you have an automatic without electronic front motor mount you can replace both front and rear rubber mounts with the ES mounts. Depending on the year, even if they are electronic you can replace with ES poly mounts, without throwing an SES code. According to the courtesy parts web page I found the motor mounts are identical from 2000-2003, but the 00-01 are electronic. So there is a harness on them which needs to be unplugged. So if you want both front and rear you are ok.
From 95-99 automatics it gets complicated. The front electronic mount on 95-99 if you have one, is larger than the ES bushing, so cannot be replaced. I have not been able to confirm which models from 95-99 have the front electronic mount. might be gxe/gle models only. But, if you have an electric mount and you can bring me a non electric motor mount bracket it can be done. Bring me the new bracket a few days early so I can swap the rubber for the ES poly.
For those of you who have signed up already I had to jack up the price a bit. I think I shortchanged myself on the labor price. Here's a link to a guy on the org who is charging 100 just to push out the bushings and mail you a used set of brackets without the bushings. overpriced I think, but when I consider that I have to make a jig to press out the old bushings, press in the new, and then do the swap in a driveway, I think 85 bucks for 3-4 hours labor is a good deal. Plus there may be the odd car with rusted bolts and may need hardware replaced (ie nuts and bolts) which I will have spares for. I will also use silver anti-seize on everything which goes back on the car.
So start up a new list and let me know if you want both front and back for an auto, and if you want the sub bushings as well.
