Can someone please help me to identify what part I need to repair/replace the half of my damaged outdoor wireless bridge.

In 2021 I purchased a pair of Cubes, product code: CubeG-5ac60adpair, the setup went fine, worked great. Until the last summer, I guess, due a lightning strike very near (I witnessed the loud bang, and the loss of link afterwards), I did not needed the link very much, even considered to bury a cable instead sometime, so I postponed the repair of my Cubes.
But now I need the link urgently. Please direct me what product I need, so I don't buy the whole thing again.
I guess only one of my Cubes are damaged. can I buy one piece? My product is discontinued, are the newer models backward compatible 80211ay vs. 802.11ad? Is the setup, configuration difficult in case I will have not a 'preconfigured pair' ? I'm confused, find no information how do the PRO, Lite models differ, can I use one of these with one of my old (5ac60ad) Cube ?
