1986 Trans Am TPI Intake Duct

Hi all! I just purchased a 1986 Firebird Trans Am with the LB9 305 TPI engine. It's a bit of a restoration project and I noticed it's missing the intake duct between the throttle body and the secondary air box. Any ideas on what I can use as a substitute or where I can find one in Canada? Thanks!!
