Hi Steve,
Here is the other larger rise/drop shank and dimensions.
Here you can see there is 5" from top bolt to top of ball. Note: This is the 3 piece head with 1 1/4" hi rise ball. Your new all cast head is about 1/2" higher. But you only have a 1" rise. So call your head 5 1/4" to top of ball from top bolt
And here is the sketch again on the small rise shank
Now the large drop/rise shank. Note: I have this in drop mode but you can see the dimensions from the top of shank to center of the holes. If you add 5 1/4" from the top hole you want to pick on that shank, it will tell you how high you will be above the top of the shank on the truck
And your truck, ground to top of shank is 21 3/8"
Since the actual hitch head has 3.75" between the bolts, you can really only adjust the head up in 3 positions.
So in shank rise mode using 5 1/4" on your 1 piece cast head with 1" high rise ball, and 21 3/8" truck height
Lowest position is: 10.5" top of shank to top of ball + 21.38 = 31.88
Next position up is: 11.75" top of shank to top of ball + 21.38 = 33.13
Highest position up is: 13" top of shank to top of ball + 21.38 = 34.38
Since your trailer is 31.5" ball height + 1.5" for squat = 33" ground to top of ball on the truck before WD. That larger rise shank in the second hole from the top should do it. And you can go up 1 hole and down one hole if you need. It should work out about perfect.
Now to the serrated washer tilt. This head is the older 3 piece head. My all cast head is at my sons house. As you can see, the slot cuts out a large part of the serrations as it is.
Full forward tilt
Full rear tilt
The serrated washer on full rear tilt.
Hope this helps
