Nothing new, but put the bed (which had been stored outside) on the rolling stand I made for moving the cab around, and brought it into the shop.
Did some thinking and measuring, and things were not adding up at all. It was looking like I shortened the rear of the frame WAY too much. Oh no!
I scoured the internet, I looked for lots of pictures of a stepside frame, and couldn't figure out why the rear bolts won't meet the frame. I had cut 8" off the back.
Oh but wait.
A stepside bed is 14.5" shorter in the front, and 5.5" shorter in the back, to equal 20".
So the 5.5" the back moves, PLUS the extra 2.5" at the front, is 8".
I'm good. Whew!
Not entirely sure the bed mount holes behind the axle are really where I want them, but I can make something work.
