Is the GM motor mount bracket the same for all LS C5 engines or should i just use different brackets all together? Pissed since i was hoping to get the motor in this weekend for measurement. The guy at GM told me yes but how quickly he barely looked at the screen and gave me the answer I'm not believing him.

Left/ Driver 10260642 ----fits fine

Right/ Passenger 10260643---- doesn't fit right pictures attached

Any help would be wonderful on this.
