I completely blew up my 1981 Nacra 5.2 traveler car, bearings, sheaves, turning block, etc.

When it went with a pop, all that stuff became air born and went into the drink...well except for the non-captive bearings that dribbled out and then into the drink.

All I have left is the main block, traveler car skeleton and track.

Where can I get a replacement traveler car and all the related pieces and parts, with captive bearings that will fit the existing track????
