Poly Trans Mount Help

I installed a poly trans mount on my car over the weekend while I was changing a bunch of other stuff. So my problem is this, there is no way that my crossmember will line up with the center hole on the mount. So I installed it on one of the outer holes. My question is this, Am I going to have any problems with this setup, and has anyone else had any similar problems with their poly trans mount. BTW my mount is from Energy Suspension.

my ES mount aligned easily, i had to enlarge the center hole on the cross member as it would not fit the bolt/stud.

Make sure it is facing the right direction also...

I had the same issue Travis. The center hole in the crossmember had to be enlarged to fit the bolt.

Yup, uses a larger bolt than the stock one.

Just file the slot a little wider.

I also had to enlarge the slot on the crossmember, and I do have the mount oriented correctly, the curved side of the mount toward the rear of the car as per the instructions. but like I said the center hole on the mount will not line up on my car. I had to use the far left bolt hole. (the mount has three holes in the bottom for the two different types of trans mounts that it will replace. I had to use the one hole on the left side.
