Looking for a Block with 80mm Diagonal Pitch ( Gforce 4 )

[Hazeno]

Ok guys and gals, I don't mind if it's from china but I am after a specific block x2 so that I can liquid cool an OG XBOX.

NO i don't care that it's worthless, or a waste. It's something I want to do.

Now onto the nitty gritty:
I have Hunted all day, and the CPU uses a Geforce 4 Mounting system so that's 50x63 with a diagonal pitch of 80mm. Attached is a picture.
Next there's only 2 mount holes I can use which would be 80mm again but OFF centre so I preferably would need either a big block or a block that has mounting brackets i can move but STILL keep the 80mm spacing. Attached is a block that is 76mm so not quite fit for purpose but gives a general idea. I WAS going to use the Koolance GPU-200 but that is just not plausible as it's not available anywhere.

Are there ANY blocks that can achieve what I am looking for? THe 80mm Diagonal pitch is the most important along with block size.

 

I've added a picture of the Iceberq Pro 4's to show the rough space I have to deal with , and how upgraded copper heatsinks HAS been done.
