I'm getting the motor mounts replaced on my G35 07 Sport sedan. The parts catalog calls for an 11220-JK00A for both sides, though while I was researching online I found on eBay that the G37 mounts worked as well, with part numbers 11220-JK30A and JK30B, for driver and passenger sides. Aside from the part numbers being different along with the prices, all three look IDENTICAL. Can someone shed some light on if they are all the same part? I don't want to buy the wrong set for the car, though the G37 ones are cheaper...
