Peter337 is quite correct in the fact that you can't just fit this kit to an aircraft but I can give the new owner a copy of the worksheets covering the removal of the kit, this will give any EASA145 radio shop the provenance they need to test or rectify the kit and issue a form 1.
I would expect all of these boxes to be quite useful for parts, the thing that usually writes off KR85's is the unavalabiity of the switch gear, this is good on these boxes and these parts can be recovered.
Sorry Pete....... I have no KR86 parts.
