Step 3: Parts and tools needed
===================
4 5x20MM Panhead Machine Screws (Keep length between 20 and 40 MM)
4 5x15MM Panhead Machine Screw (Must be no longer than 15MM!)
44 #10 Washers
===================
And for your English measurements (Thanks to ajmontag for providing these):
***********************
4 3/16" x 1" Panhead Machine Screws
4 3/16" x 1/2" Panhead Machine Screws
44 #10 Washers
***********************
These 5x20MM(3/16"x1") screws will be used to secure the CPU heatsink.
The shorter screws will be used for the GPU, and 15MM is the most you can get into it. The 1/2" fits just fine with room to breathe.
About 44 #10 washers. These will be used to keep the motherboard firmly in one position. Nylon washers aren't necessary, there are no traces or components to be touched around the screw holes. But if you feel you must have them, I will not stop you from purchasing them.
And while you are working with the heatsinks, you may want to apply new and better thermal paste to them. I suggest picking up a tube of Artic Silver 5.
Toolwise, you'll need:
A drill or drillpress to widen screwholes in the metal case(with a 3/16 drillbit)
A torx 9 and torx 6 screwdriver to remove screws from the 360's case
A 1/4 inch wrench or socket to remove the X-Clamp posts from the heatsinks
A phillips-head screwdriver for those machine screws(or flathead if that's what you got)
And a tiny flathead screwdriver to pry off the X-Clamps.
Anything else like tape and steel scrubbers should be kicking around in your house.

And The 3/16" x 1/2" Pan Head Machine Screws
And The 10# Washers
Anyone else run in to this problem? I'm going to try and run to the hardware store and find some smaller screws and report back. . .
Also, I couldn't fit washers side by side and needed to clip the washers. Nylon washers are much easier to clip. BUT, the nylon washers I got were thicker than the metal ones, so take that into account when stacking. I would say 2 nylon washers are the equivalent of 3 metal washers in thickness.
Is there anything else that can cause rod other than the x-clamps?
I went to lowes today also...and got 6-32....not the same!! ahah wow, we fail, but i kinda was convinced that it was the same from a fraction view (6/32 = 3/16)
1. You will still need to drill larger holes in the metal frame so that the bottom of the pins can protrude through.
2. On the gold heat sink, you will need to bend (VERY SLIGHTLY) the x-shaped bracket to get it closer to the board. I did this using a crescent wrench.
3. Lastly, when attaching the silver heat sink, the threads of the screws just barely make it. Don't tighten down too far on the end that sticks out, there are some additional resistors there that look like they could get shorted by the heat sink. Look closely to make sure there is clearance.
To settle any confusion with the washers I used (4) 5mm washers on each screw and that provided the perfec amount of space. Then I used a 5mm grommet between the motherboard and the heatsink to give a snug fit to both processors. This helps with the amount of tension that should be on each screw. I spent hours getting the tension right and the grommets helped once I took it apart and put it back together using them.
All in all thanks for the fix. It saved me $200!
I agree with what Reklis said. i did the screws the washers and then a little rubber grommet between the heat sink and the motherboard. tightened it until it touch the CPU/GPU and it worked perfectly.
