A: Crank spacer, special flexplate (modded GM one)and same starter as the '77 AMX I parted. (the flexplate and starter in my '73 J4000 were both toasted from the PO attempting to start the seized motor) From: <mail@xxxxxxxxxxxx> To: mail@xxxxxxxxxxxx Subject: Re: 1966 Jeep Wagoneer needs to go ASAP FYI, actually you can only run a Buick Nailhead Turbo 400 trasnw ith that adapter. I believe you also need a crank spacer and there may be a special nose on the starter too. I haven't actually taken mine apart yet.
