Flywheel ,ringgear.gear reduction starter guestion

[mallard]

I have a bolt on ringgear flywheel assembly for my 56 TR3. I know it is not correct but that's what came with the car. The previous owner used it that way and it distroyed the ringgear and clutch because thay were using the bullnose starter. I know I have to use a gear reduction starter because the Transmission housing will not except the the correct late starter drive. My question is do I need or should I turn the ringgear over on the flywheel so it will engage with the pinion on the side with the angle cut, or the straight cut? The original starter for this would have had a pinion that came back to the starter, not one the drives out to the starter like the gear reduction style. Also does the correct gear reduction starter for the bolt on style have the pinion gear with the 10 teeth? Please look at the pictures to help explain.

Last one.
10 teeth.

The gear reduction starter can be used with the ring gear teeth either way.

The bevel on the ring gear teeth is only needed for the Bendix-type starters (where the pinion is already turning when it touches the ring gear). I've been running mine for quite a few years with the gear-drive starter engaging the flat side (in fact I just moved that setup to the project TR3 a few days ago), and it works great.

10 teeth on the pinion is correct for the bolt-on ring gear. 9 teeth is for the earlier, press-on ring gear.

Worth noting perhaps, that some TR6 came from the factory this way. They didn't bother flipping the gear over, after they switched to the pre-engaged starter design.
