Motor Mount install prices/Only 1 new mount Installed

[Peabody]

HI, I have two questions. After having problems with my hotshot header hitting the steering rod knuckle under hard take off when turning and having the steering wheel almost lock up at times due to the knuckle hitting the header. We tried to put a small dimple in the header so that we would have more clearance. My muffler shop noticed that the drivers motor mount was shot. He thinks that the torque of the motor is lifting the motor and the knuckle is rubbing the header causing the feel of the stearing wheel sticking when turning. Anyway, I found a new left Nismo mount on Ebay and got it for $75 shipped. Do I have to change out my right side to a Nismo because it is the stock mount. I have had all 3 mounts(Left, Right, Trans) changed out about 50,000 miles ago. Is it OK to have a Left Nismo and leave the stock right on? About how much will a shop charge to install the left mount? It looks easy, but I cannot work on my car because I have a ruptured disk and need surgery. I have a friend that said he would do it if I just told him what to do and watch him because I cannot help do anything with this bad back.Thanks

I guess my question is what is a fair price that a shop would charge to install the drivers mount and do I need to have to get a Nismo for the pass side?
