I have a 2013 ex cab short bed and right now I have a 4/7 drop with 22 inch tbss wheels. I am wanting to go down to a 6/9 or 7/10 but I know that I need to go to a 2 piece shaft but wasn't sure what I need to get one from and what all I need to do it (ie. crossmember or make one) Any help would be appreciated. I don't live near where anyone goes this low static to look at others trucks or anything!
