now it's Jan 2021 and time to build it...rolled into the shop...working on the rear of the truck first...I still need to trim off 5" of the rear of the frame so the short bed will fit...i did get the rear crossmember relocated forward...here's a pic of the 1" lift shackle...that's right, I'm going up instead of lower on this one....now for a new diff cover, brake lines ordered, new rear brakes, some paint
