Finlandese,
Afraid I know nothing about the rack on a Longchamp but if I were you my first choice of someone knowledgeable in Europe would be Roland Jaeckel in Germany. Roland supplies many factory DeTomaso parts for all their different models & may well be able to answer all of your questions. Try e-mailing him at "Jaeckel-Partner-GMBH at t-online.de" & good luck.
