WTB 1985-88 TPI, MAF to Throttle Body Adapter

Does anyone have an extra one lying around? I could use it to finish my 383 CAI on a 1989 GTA. Small opening measures 3 1/4" and throttle body side measures 4 1/2". Looking for the durable rubber piece, not hard plastic...LOL. I just bought one off of e-bay and it was hard plastic, junk!
Let me know and THANKS!

Bellows...? I didn't know it was called that. Maybe that's why I can't find one...
