TCAS or not TCAS?

My 73 T337 G (P model) once had a Ryan 9900BX installed for traffic. A prior owner left the processor in the garage one too many nights and his wife sold it on EBay!

So as I get ready for my avionics upgrade in April, I’m wonderIng if I should find a box and have it reinstalled? It’s already wired for power and antennas and feeds the Garmin 530w.

Rest of the story: In order to get ADSB legal, my upgrade transponder was installed early. As I read about the options it has, it looks like the Ryan 9900BX is not needed at all and that the L3 NGT 9000 unit can use the antennas installed and provide active traffic.

I might be missing something about this technology, can anyone confirm my suspicion that I’ll have active traffic just like from a Ryan unit?
