Short answer? NO! I had both side by side, and the F10 transmission is about an inch (25mm) wider across than the one off my 1990 carry. The F10 trany is off a super carry, a 1000 cc variant. To swap the 1000cc engine into the 660 chassis would be a pain also, because all the mounts are different, and some are welded to the frames in different locations. Not saying it couldn't be done............ with some fabrication. It's just not a matter of changing parts. Too bad, I was hoping when my carry engine dies, I had a replacement. Here's a pic of the two
Oh, by the way, I needed to change the throwout bearing on my 660cc truck, and just had the 1000cc engine/trany hanging around, so I had figured I'd check to see if the throwout bearings were the same. Turns out they are, so I didn't need to buy a new one.
