The Ford LN8000/LNT8000 and the Peterbilt 359 "California Hauler" do not have hinged hoods. You'll have to scratch build a hinge. I hinged thr hood on my 1973 Ryder Ford LN8000 Short Hauler with aluminum tube & some steel rod. Works quite well, actually.
It's hard to tell from this pic, but you can just see the two small tubes on the front of the frame where the pins from the hood would sit.
I filed out a nice little groove for them & epoxyed them in. There is a corresponding tube epoxyed to the hood. Then a rod connects them all together.
