I have a 1955 180 with the PPonk O-470-50 motor with dual exhaust hanging on the original J mount. I am looking for anyone that has exchanged the J engine mount for the 185 floatplane mount PN 0751003-31 (has the tip out mount brackets on the lower firewall attach points). I have seen this engine mount combination on a 1955 with dual exhaust so I know it will work. My question is what brackets are used on the lower attach points? The "Lug-Engine Mount" PN 0751006-2 called out in the 185 parts manual is to short to fit through the aluminum bushing that go through the firewall. I have already contacted Acorn Welding and Seaplanes West and they have been very helpful but unable to help me. Thank you for any help.
