Thanks for the quick reply.

That is good to know. I'm also finding the clutch assembly is also pricey and sometimes rebuilt. I'm going to order a Denso compressor and a Mahle drier. I'm hoping the Denso part # is 4711228 about $288 with tax and the Mahle is for Mercedes part 1248300283 about $30.

Still looking for installation instructions since my computer access is gone due to ' flash ' no longer supported. Also couldn't get 124performance.com to work for the same reason.
