If you need mounting hardware for your 8045, then just order the hardware to mount a Swiftech MCX 462. It is the same hardware as Alpha's. You can get the hardware directly from swiftnets.com, go to "where to buy" and choose "online store". Scroll down a bit and you'll see the mounting hardware kit listed for $4.15. I know the hardware is interchangable because I own both heatsinks and have interchanged them on each hardware kit. Hope this helps you out.
