The layout is about the same, just decorated differently, with the additions of a few sections.
Where it changes vastly is on features, some available to us regular users and mods, but more so on the Admin side.
Even though it is for an NA steering system. This write up should help you a bit.

The OEM color, on the earlier models, is the one you see at the top of the pot, that green/brown-ish shade. I'd rather have it painted black or any colour of your choice.
If you are able to find a US spec engine oil cooler in decent condition you could re purpose that as you power steering cooler.
If that is not an option, this is will get the job done just fine, albeit some minor modification will be required to mount it.

The smaller cooler is the transmission oil cooler.
Also highly recommended that you replace the engine oil cooler with an upgraded unit, while you're at it.
Wait!...so the AMG's will clear the inside double lip of the Veilsides and the SRT8's won't?
What size rotor will you be using for the AMG's?
Very interested on this as both my Blitz and my SSR's have a double lips inside.
