48 IDA Webers were homologated for the Gr-3 and Gr-4 but were options. The Holley #213 (list 4778) was the carb mostly used, I think. You do know there's a Swedish-run Registry for Gr-3 Panteras with a 14 page Supplemental Parts List that covers Gr- 3 and 4 parts. Browse to www.scuderiadetomaso.se, run by Anders Hellburg. He's still active- got an e-mail from him last week.
