Mike,

The amp will fit just fine with your current configuration. Although, the 
KAT2 and KIO2 boards will stay with the original top cover. The KPA100 
includes the KIO2 circuitry. If you need an ATU for use with the KPA100, 
then you will want a KAT100 ATU or other brand that can handle 100+ watts.

Hope this answers your question.
