Where you guys placing the ECU on 65 Cudas/A bodies?

Hi Guys,
My 65 cuda currently has its ECU spliced into the factory points engine harness, and it is a mess of cobbled up wires. I'm looking to buy a new one thru Evans wiring for $110.00. He however says the ones that he has are designed to be placed next to passenger valve cover. I have AC, so my firewall on that side is full. The current spliced one sits on the Middle of the fender well on Passenger side, but his does not have enough length to reach there. Any suggestions, or Pix of where you guys have yours placed, or anyone that has bought one from him and made it work with AC.
Thanks a bunch,
Highway star
