I would cut the tabs off the flywheel. I believe they are there to
cool the torque converter. They actually consume a bit of HP at
high RPM.

Perhaps you can use that first one later with a smaller center to
center
distance.

Do you agree the tabs will have to be milled off to exactly the
same height  so that no imbalances are created? The entire tab
would not have to be removed.  Just enough to gain clearance.

I think you can do a good enough job with grinder. Just make a
template to check the height of all of them.

You could also  check the
flywheel by bolting it to a shaft and balancing it between two
horizontal knife edges. My hangar neighbor just got done balancing a
19 inch spinner and backing plate for a Nemesis Next using that trick.
Another even easier way is to machine a hub and balance it on top of a
vertical point made from steel. Old wheel balancers were made that
way. As I recall they had a semi spherical bubble level to make sure
it was horizontal. Maybe the local gas station has one of those old
wheel balancers lying around.
