Local had a 5.3 engine/trans just like mine so I used it to locate the mounts and build the K member. Also, here is a picture of the donor car for my engine and trans. It had been setting around for 5 years when I got it. Engine happens to be an all aluminum 5.3 designated LM4. Only produced 2003/04. Drops about 100 lbs from the iron block. I'll need the savings because of the much beefier frame.
