Report P/N 1701162 Temp Knob - What Does It Fit? in 1965-83 Avanti Posted Tuesday at 11:16 PM · Edited Tuesday at 11:19 PM by Gunslinger It’s not a Studebaker part but one sourced by Avanti Motors…sometime from the mid-70s or ‘80s. I may have some lists that give a more accurate time frame but I don’t have access to it at the moment. One way to tell whether a part is originally a Studebaker part and still used by Avanti Motors is the part number…most Studebaker parts numbers began with “15xxx” and parts sourced later for changes by Avanti Motors were “17xxx”. Avanti Motors would change parts for several reasons…a genuine improvement…they ran out of original Studebaker parts…a changed forced by government requirements…forced by circumstances such as General Motors changing engine and drivetrain specs.
