[W126 Coupe] AMG Staggered Wheels at The Wheel Exchange

[Vince]

Hi folks,

I have been trying to do my research on the archives and seem to see that
the AMG Mono Bloc II would be a good choice for my 1988 560 SEC.   The Wheel
Exchange can get a set of 18 x 8 and 18 x 9 for 1400 plus shipping.  They
claim that they will fit, but with spacers.  They are not sure of what size
would be required.  Several questions:

1. What size spacers would be required?
2.  What should I ask about ET?
3. Who else would stock these wheels and really know what they are doing?
4. What other wheel recommendations would you have?

Thanks in advance for your help!
