Update!

OK so I finally decided... yeah its time to do this!

Took soem legwork. Using the VIN, I used Toyota DIY to get the original Toy part #.
Then some googling around w/ that number, found a site w/ the part measurements. Its the larger 9 1/4" flywheel. Which, if it were a true hard cuttoff at 11/92, it shouldn't be, so glad I checked ;-)

Now of to start tearing it apart to change out.

With 200+ Billion electrical parts, the world most complicated machine is inside your own skull.

Question Reality.
