Your frame looks quite similar to mine though your tank appears much further forward than mine. Mine is back against the rear cross brace where the frame levels out. Yours appears to be forward on the upslope. Wondering if your Diff pumpkin will strike the tank in its current position.
The tanks are the same, yours and mine.
I did not notch the frame....merely cold bent a lip in the DS frame rail to add a bit of clearance for installing the filler band clamps. Simple job with an adjustable wrench and bent the lip 1" in from the edge and about 1" to either side of the filler neck. However, Had I installed the rubber fill hose first, no bend was likely to be needed.
Sliding the tank rearward all the way to the rear cross brace accomplished three things...
1 No interference with the diff.
2 Got the fill neck far enough back for easier access around the bed sill (the rear one that bolts bed to frame - its the one I notched to raise the tank as high as it would go)
3. Got the 1/2" dia vent tube out from under the same bed sill....just enough rear of the sill to install the vent hose and not have the entire assembly inside the sill and butting up against the bolt that holds the bed to frame on the DS side.
