In David K.'s assembly thread, he has several posts and pics, starting on page seven, of them dropping the drive train in. Unlike my ERA, where you drop the engine in without the transmission, and then put the transmission in after the fact, David's thread has them dropping the complete engine and transmission in as a package. What I would do is call David K. up and just ask him if it would be easier to take the "pull trans only" method or do you really have to pull the whole package just to get to the flywheel. If no one answers the phone, then shoot Morris a PM. I guarantee he knows the answer. And here's a direct link to the motor/trans drop in:
