Generation IV Internal Engine - A/C block help? GM RANT

Does anyone have any idea where you can purchase the block that bolts onto the CTSV A/C compressor? I called Docs blocks, and was told they don't have it. I have heard they are getting out of that business. I find it odd, that GM is selling all of these LS3 E-rod engines, and NO WHERE in their catalog do they list this part. I can't find ANYONE who has it. SD told me that I would just have to buy the lines for a CTSV and "make them work" That should look nice. :bs:

Thanks for any help!
