LM23P9B137105 Dart Swinger 340

Hi guys.
Looking for my late brother's 1969 Swinger 340 Dart. The VIN is listed in the thread title. Last I was aware, it was registered in Connecticut in 2002, but I lost track of it since. Car was in either Southbury CT or Southington CT.
Originally painted red, black interior, black vinyl top and black bee stripe, it was a 340 with an automatic trans. Any info will be greatly appreciated!!

Thanks,
