Adapter Plate
Jim and I spent an hour drilling the holes in the adapter plate. I marked the hole centers with a punch directly over a print out from the design. I'm still trying to work out how to cut a 3 inch hole in the center. The motor arrives soon so I can remeasure the mounting holes and try them in the adapter template.

Motor Coupler
This is a Lovejoy L110 jaw style shaft coupler body ($44 from http://grainger.com). I went with the L110 because the outside diameter (OD) is 3.32 inches and the slot on the flywheel is 3.1 inches. It will have to be trimmed slightly to fit. The L100 is only 2.54 inches so it would not have been wide enough to fit the flywheel holes.
The The center bore is 1.125 with a .25 x .125 keyway, which matches the L91 motor shaft. It has 3 "teeth" that would normally mesh with another coupler on the drive shaft. I'm planning on cutting the teeth off and drilling and tapping holes to match the flywheel. The flywheel will need to be skimmed down to fit inside the adapter plate in order to retain the "magic number", which I measured as .665 inches. The design program shows the magic number as .78 inches.
Coupler and Adapter plate
This is a lovejoy L110 connector for the coupler and a sheet of 6061 Aluminum for the adapter plate. I've printed out a plan from http://metricmind.com and traced it onto a plywood sheet for a mockup of the adapter plate. With the holes drilled, it only need a little trimming around the bellhousing mount and the transaxle. So I started in on the aluminum, which I got from a local welding shop for $75. I noticed a few metal shops on ebay selling the same thing for in the neighborhood of $15 plus shipping.
To cut the plate I used a hand held electric jigsaw and a 24TPI (tooth per inch) metal blade. The 24TPI blade created a really smooth cut and WD-40 worked great for cutting oil, very light. A friend has a drill press to cut the holes and center hole.

Out with the old
This is the old ICE engine stripped down. I was able to lift it by myself so it can't be much over 100 lbs. We used a cable winch (come-a-long) to hoist it away from the transmission. Notice the 2 inch hole on the lower right side of the block. I guess a rebuild of this isn't going to happen anytime soon.

Removal of all the gas parts.
We finally got the engine out. The clutch and flywheel are still on the engine. There is a huge hole in the side of the engine block. I guess that's why the car was so cheap.
Tomorrow is degreasing the engine compartment and cleaning up the interior. I would have degreased the engine before beginning. Also, I would have removed the belt pulley first, which would have made getting the engine out easier.
