They don't list an Audi kit, and you don't need to buy a whole kit
from them.  Just buy the bracket and hardware and source the rest of
your parts elsewhere.  Their bracket is a nice cast aluminum piece and
the mounting to the "York" side is actually four slots that allows you
to adjust the forward and backward alignment to line up the belts.

You can use the stock tension adjustment.

> Are the Sanden's any deeper/longer than the Yorks?  I don't want to run into any problems with some unforseen other component.  The idea would be to use this setup in an MC-1-converted 4kstq, urq-style I guess.

The Sanden compressors' dimensions are listed on their web site.
You can find the York's dimensions in this document:

You can do a little homework and measuring of your own, looking in
your engine bay.  Allow some extra room for the hoses and fittings.

If you're going to convert to the UrQ style, be aware that the UrQ uses
the Mini York compressor instead of the standard York.  My 4000 (being a
4-cylinder car) also uses the Mini York with the compressor mounted
on the exhaust side of the engine.  You can identify a mini York by
its entirely cubic shape, including the top and bottom plates.  The
standard York is also cubic, but larger with a sort-of hexagonal shaped
top/bottom plates.  ICE makes Sanden adapter brackets for both the York
and the Mini York applications.

You can see pictures of the Sanden compressor installed in my 4000
with the ICE bracket and all, at my web site:

You can pretty much make this whole thing a DIY project, and only
let an A/C shop do the following:

	- Evacuate stock A/C system of R-12 and mineral oil
	- Fabricate new barrier hoses (if you're replacing hoses)
	- R/R expansion valve (if you're going to do that)
	- Recharge system with R-134a

This will save you money, and if you are going to be replacing the hoses
and expansion valve, you can do the prep work of removing the glove
compartment and the evaporator drain tray to minimize labor costs,
and ensure that no monkey lad is going to break something trying to
take your glove compartment apart.
