Well youneed to provide more info about your vehicle to know anything... And 3.73's are not harder on the rear or tranny unless not set up right...

Yes, as far as factory GM RPO production components. Only aftermarket gear suppliers provide a gear set that will provide a ring and pinion gear that will allow mounting a 3.23 ratio on a series 2 carrier.
And no, GM never used spacers to adapt 2 series carrier - 3 series R&P components.

Easiest way to determine if you have a 2 series or 3 series is; can you select the 1 on your shift console? If not then you have 2.73s and a 2 series carrier.
