[Elecraft] KX3-2M TO-220 Retainer and Nylon Screw

[AL7CR]

Does anyone know if these parts are a recent change?  My pal is sending me his board and it did not have these parts.  The heat sink was attached to the case directly with a metal screw and the nylon screw was not present and the hole for it empty.

If the parts are strictly required I will try and get them from the factory tomorrow.

Thanks for the help.
