I have a 2004 crew cab 2wd 1500 lifted but wanting to lower it. I found out I need to notch a crossmember, anyone know which one and if they sell after market bolt on members? Thanks in advance!

 

Notch a crossmember?

 

yes they say I need to notch a crossmember so it doesn’t hit the drive line for a one piece drive line
