The process boils down to this:
1) Adjust the cab to factory specs. Since you don't have a manual, you probably don't have the cab set to specs above the frame.
2) Adjust the back of the hood to the cowl so that you have a parallel gap the full length of 3/16" to 1/4". This is when you set the correct height of the radiator support. The gap won't be parallel if the radiator support is not spaced correctly.
There is a lot more in the manual, but this should get you headed in the right direction.
Your life will be much easier once you buy a manual.
Which manual? I have an assembly manual, it gives me measurements, etc. The cab is sitting as per that manual's floor/frame distances. How do you adjust the hood to cowl gap?
