SA Carbon modifiers extension keys

[Yuubin]

Dear all,

I am looking for these keys from the SA Carbon modifiers extension kit:

R4 SHIFT (1.75u)
R3 PAGE UP
R3 PAGE DOWN

If you have these and don't need them, please let me know. I am willing to pay or trade (e. g. any keys from the SA Carbon warning signs kit).

Thank you
Yuubin
