I have the same rear crossmember for my duramax as well and was wondering what each of the three different bolts and nuts were for. I’m guessing the size that just has one set is for the spare tire hanger but no clue where the other two sets are supposed to go, one is longer than the other.
@@charliehage189 when I put this one in the longer bolts go threw your rear leafspring shackle hanger. The bolt comes threw the new cross member, frame rail as well as the spring hanger but only the front 2 on either side. If you go to the 4 minute mark you can see the new bolts
