Help with PB rear notch install
Well tore my burb down getting ready to install the notches. My question is what are the referance points for cutting the frame? I hold it up and can eyeball it but was just wondering how the other guys measured and cut. Pics would be great.
Thanks

Do you have the new "mild drop" notch?

Re: Help with PB rear notch install
As per Nate, the centerline is supposed to be 29" back from the rear-most rivet centerline of the flat box mounting bracket. This is measured along the top of the frame. I have attached a pic of my mockup as well, which Nate said looked correct. The triangular group of rivet holes is where the axle bump-stop used to be.
I know things look kinda wonky in the pic in regards to the axle centerline, but it all works out in the end! Hope this helps! Or at least was remotely coherent! Jason

Re: Help with PB rear notch install
Would the notch be in the same place on the short beds also?
