Guys, thanks for the suggestions. I did speak with Eibach this AM and he said it's going to be a matter of trial and error and said it's entirely possible the pads already installed (#2 in rear, #5 in front) could be fine. He suggested there's a good chance of this unless I find the ride height too high in front which means I'll need to get thinner pads all around. The Eibach springs should be about 1/8" taller than the H&R (which is fine with me).

Problem is, the diesel engine is very heavy compared to the other powerplants and is the reason I have such thick pads up front. He felt most of the cars would leave the factory with pads, and depending on local bumper height regulations and options on the vehicle, there may be thicker pads in some cars compared to other.

I don't think I am going to be able to pre-purchase more pads without completing the entire installation and determining how things level out and how the final ride height looks.
