Default Motorola EB63 Power Amp

Any one ever build one of these? I got a kit of parts from an SK buddy of mine, but there were no instructions or parts layout diagrams. The EB63 is a 2-30mhz 100w power amp. It uses two MRF454 transistors and can put out 100w with 5w input. The barebones 'kit' is put out by Communication Concepts Inc. The problem I have, is, my circuit board is marked EB63a and the COR relay is encapsulated where the EB63 relay is open. So, the circuit board is a little different from the one at the CCI site. I have downloaded the Engineering Bulletin and schematic, but I need a parts layout diagram. I have also sent an email to CCI requesting assistance, but have not heard anything yet.
Here is a picture and schematic of it from the CCI site:
