This is not a recommendation for anyones mounts but just something we did to eliminate some of the issues we had.
I did chose to use Destroked mounts because they use factory 3rd gen Dodge captured mounts and engine brackets.
The recommended setback to run a mechanical fan is 2 3/4", this is also the amount the crossmember moves when moved to the back holes in the frame on auto trans trucks. In diesel ZF trucks the crossmember is already back requiring mods to the crossmember.
Once we got the engine set in it set at the same 5 degree tilt as the PS engine, but it was to high, the trans and bell housing where jammed into the tunnel shield and the mechanical fan stuck up above the radiator, no way could you remove the back valve cover without lowering the engine or trans.
The hole works looked like chit!
The mounts came with 1/2" plates that bolted to the block allowing the left mount to be moved back to clear the PS pump.
After taking the mounts loose from the engine we lowered the engine down to a 2 1/2 degree tilt, this gave us 3/4"- 1" clearance above the crossmember, moved the trans and bell housing away from the tunnel and centered the mechanical fan in a 7.3 shroud, as a bonus the rear valve cover could be easily removed.
We decided to make a new set of 1/2" plates that would allow us to relocate the engine brackets higher up on the block. Our measurements showed the engine mount brackets needed to move up 1" which allowed the front of the engine to drop nearly 3".
Unfortunately I forgot the take pics of the brackets before installing the engine but here's what they look like with the engine installed.
This is the right side mount, the beige colored bolts hold the 1/2" plate to the block, the black bolts thread into the plate holding the mount, some clearancing on the mount was needed for the back bolts as well as a SHCS bolt used in the bottom hole under the mount. The mounts are moved up 1" and offset to allow room for the bolts

This is the only good photo I have of the left side but you can see the mount sets high up on the plate

You can see the oil pan is pretty close to the crossmember and the steering stabilizer clears the pan by less than 1/2"
Note: We did a coil spring front conversion while the engine was out, leaf spring steering stabilizer is located differently.

Fan centered in the shroud with enough room to remove the fan without pulling the radiator.
We did cut 1/2 - 3/4" off the back of the shroud to better access the belt tensioner.

Lowering the engine did require notching the front crossmember for the AC compressor manifold.
We welded in a piece of angle iron upside down to fill in the hole

In this pic you can see the notch better

Here's a pic of the truck and trailer it's hooked to 90% of the time.
Truck weighs 9500 lbs
Trailer weighs 6500 lbs
Grossing 26000 lbs in the photo.
It's only making around 325 hp but with over 700 lb ft torque below 2700 rpm it pulls like a beast.
