You will be playing Russian Roulette by using either of the set-ups.
If it was easy GM differentials would all have the same shims or even better, none at all.

That said, you could get lucky? If I was lucky using the shim set from the original gears may be your best option.

I recommend purchasing a new set of bearings and starting over like you were installing a new gear set, which in essence is what you are doing.
