I believe it all comes back to the bell housing issue. Seeing as the spi uses the ITB? and the zetec uses the mtx75.

The duratec and zetec use the mtx-75, but the only difference is the bell housing. So maybe thats the same with the spi and zetec auto.

The SPI and Zetec have the same bell housing.

But you'll have to use the Zetec Flywheel, that requires bushing spacer for the flywheel bolts since the Zetec uses larger dia bolts.
