[Elecraft] Missing thermal pad in KAT500 kit

[WM3M]

I just got my long awaited KAT500 kit today.
The thermal pad for R6, figure 12, is missing.
I checked and re-checked all packed areas, it is not there.
Can I proceed to assemble without it or use something else in its place?
I really would like to get it working today if possible and not have to wait till mid next week.
I don’t think there is any place near me where I could buy one.
Any help or ideas is appreciated.  Thanks 73
