Is Quick Lock Sink Mount Reusable

I am replacing my Insinkerator Septic Disposer (circa 2002, see photo) for a new model Insinkerator Evolution Excel 1 HP model. I looks like the quick lock sink mount is identical and it would greatly simplify the installation if I could simply switch out units, rather than reinstall the sink mount. The new model is heavier due to larger motor. It is a stainless steel sink and the plumber who installed it recently reinstalled the old disposal unit with sink mount when I replaced the sink. Can I use the old sink mount for the new disposal unit or do I have to switch everything out?
