does a 2003 silverado 4.8l have the same mounts and wiring harness as a 2006 6.0l. i know the 6.ol wont go right into a 2000 for those differances but i think the 2003 and 2006 are the same generation? i know that i ll get the right answer from a handfull members here. it may not be what i want to hear but i ll get my answer. thanks in advance
