So I am still looking for a way to bring my input shaft .5" to my flywheel. The Aisin transmissions cannot swap input shafts with other models if they are of a different first gear ratio. So swapping to the longer Isuzu AR-5 input shaft is out.

I called around on having a custom flywheel made and this is looking like a $450-500 solution.

I also called around some clutch resurfacing shops and they had never heard of changing a clutch offset so I think a custom clutch is out too.

I think I am down to a flywheel spacer/adapter. This is just a draft , with no real measurements. Holes are just for illustration for now.





This will push the flywheel out .5". It will have a snout on the crank side to center it, and the other side will support a Toyota pilot bushing so I don't have to get one made. Pics are from emachineshop.com and their software.

This will still leave the problem of starter engagement and my bolts will have to be .5" longer so there might be some more stress here. Not sure if I this would be a problem.
