Me and a friend are dropping a 6.0L LQ4 in his 4.3L 99 reg cab chevy. Are the motor mounts the same? We are ready to pull the 4.3 out tomorrow. Just by looking at the motor mounts it looks like they are the same size and in the same location. Does any have a clue to the answer? A quick response would be appreciated. Also, does anyone know if the exaust will be the same where it bolts up to the headers? Thanks again guys!
