Message	I've had to grind a couple NA bellhousings to clear a TT flywheel but some have been the same dimensions inside so no grinding. The starter spacing will be different to clear the larger TT flywheel but only by 5mm. I wouldn't worry which one you use, at worst you will have to grind a bit around the mounting bosses for flywheel clearance and put a starter shim on. Z1 or 300 degree? make them. Maybe you could take a measurement from the centreline of the two boltholes nearest the starter pad to the pad surface and compare that dimension with the other BH. If you have the whole transmission, you can pull the speed sensor to tell if it is an NA or TT. Red or Blue gear I think. Google is your friend on that one.
