Thanks mate!
I finally got a couple Moto-Terminators, and I was going to post my findings but you beat me to it!
I did find though, that if you attach the Moto-T's in the same manner you did, only pointing up, they fit better and more sucurely.
I also found another way to hook them on. It's not quite as sturdy as hooking the "fins" on the Harvester around the "seat" on the Moto, but I have picked up the Harvester and moved it around, while they were attached, and they didn't fall off.
If you turn the Moto so that the nose is pointed down, with the wheels towards the Harvester, you can put the Moto's front wheel in between the "fins" on the back of the Harvester's leg. Then flip down the Moto's kick-stand and insert it in to the grooves marked in the picture. The friction holds it in. Though I have been thinking about using the dremel to make a couple small holes forthe kick-stand to go in to, to make it fit even more snug.
Seeing the size of the Moto's and the size of the Harvester, there really is no reason that Playmates couldn't have designed a couple of pegs, on the Harvester, for the Moto to hook on to. But then who knows if they even knew that the Moto's came from the Harvester, when they were sculpting them.
I really wish the Moto-Terminators weren't so darn expensive to import. I've got two more Harvesters that need Moto's.
